One of the pool APIs for when caller is holding lock was not defined but
is declared in rxe_pool.h. This patch adds the definition.

rxe_pool.c uses the field pool->state to mark a pool as invalid when it is
shut down and checks it in several pool APIs to verify that the pool has
not been shut down. This is unneeded because the pools are not marked
invalid unless the entire driver is being removed at which point no
functional APIs should or could be executing. This patch removes this
field and associated code.

rxe_pool.c takes references to the pool and ib_device structs for each
object allocated and also keeps an atomic num_elem count in each
pool. This is more work than is needed. Pool allocation is only called
from verbs APIs which already have references to ib_device and pools are
only diasbled when the driver is removed so no protection of the pool
addresses are needed. The elem count is used to warn if elements are still
present in a pool when it is cleaned up which is useful.

This patch eliminates the references to the ib_device and pool structs.

rxe_alloc() used the RXE_POOL_ATOMIC flag in rxe_type_info to select
GFP_ATOMIC in calls to kzalloc(). This was intended to handle cases where
an object could be created in interrupt context. This no longer occurs
since allocating those objects has moved into the core so this flag is not
necessary. An incorrect use of this flag was still present for rxe_mc_elem
objects and is removed.

The names and comments of the 'unlocked' pool APIs are very misleading and
not what was intended. This patch replaces 'rxe_xxx_nl' with
'rxe_xxx_locked' with comments indicating that the caller is expected to
hold the rxe pool lock.

A recent patch which added an 'unlocked' version of rxe_alloc introduced a
bug causing kzalloc(..., GFP_KERNEL) to be called while holding a spin
lock. This patch corrects that error.

rxe_alloc_nl() should always be called while holding the pool->pool_lock
so the 2nd argument to kzalloc there should be GFP_ATOMIC.

rxe_alloc() prior to the change only locked the code around checking that
pool->state is RXE_POOL_STATE_VALID to avoid races between working threads
and a thread shutting down the rxe driver. This patch reverts rxe_alloc()
to this behavior so the lock is not held when kzalloc() is called.

Currently, polling a umad device will always works, even if the device was
disassociated. A disassociated device should immediately return EPOLLERR
from poll(). Otherwise userspace is endlessly hung on poll() with no idea
that the device has been removed from the system.

MAD message received by the user has EINVAL error in all flows
including when the device is disassociated. That makes it impossible
for the applications to treat such flow differently.

Change it to return EIO, so the applications will be able to perform
disassociation recovery.

The cited commit disallowed creating any QP which isn't raw ethernet, reg
umr or the special UD qp for testing WC, this proved too strict.

While modify can't be done (no GIDS/GID table for example) just creating a
QP is okay.

This patch partially reverts the bellow mentioned commit and places the
restriction at the modify QP stage and not at the creation.  DEVX commands
should be used to manipulate such QPs.
