undoing - they aren't all in the right places, however.

  console: Fix compilation regression

Fix build error caused by a stale security/selinux/av_permissions.h in the $(src)
directory which will override a more recent version in $(obj) that is it
appears to strike only when building with a separate object directory.

It's harmless to set this after the server is created, but also
ineffective, since the value is only used at the time of
svc_create_pooled().  So fail the attempt, in keeping with the pattern
set by write_versions, write_{lease,grace}time and write_recoverydir.

(This could break userspace that tried to write to nfsd/max_block_size
between setting up sockets and starting the server.  However, such code
wouldn't have worked anyway, and I don't know of any examples--rpc.nfsd
in nfs-utils, probably the only user of the interface, doesn't do that.)

Commit 59db4a0c "nfsd: move more into
nfsd_startup()" inadvertently moved nfsd_versions after
nfsd_create_svc().  On older distributions using an rpc.nfsd that does
not explicitly set the list of nfsd versions, this results in
svc-create_pooled() being called with an empty versions array.  The
resulting incomplete initialization leads to a NULL dereference in
svc_process_common() the first time a client accesses the server.

Move nfsd_reset_versions() back before the svc_create_pooled(); this
time, put it closer to the svc_create_pooled() call, to make this
mistake more difficult in the future.

If a callback is retried at nfsd4_cb_recall_done() due to
some error, the returned rpc reply crashes here:

@@ -514,6 +514,7 @@ decode_cb_sequence(struct xdr_stream *xdr, struct nfsd4_cb_sequence *res,
 	u32 dummy;
 	__be32 *p;

 +	BUG_ON(!res);
 	if (res->cbs_minorversion == 0)
 		return 0;

[BUG_ON added for demonstration]

This is because the nfsd4_cb_done_sequence() has NULLed out
the task->tk_msg.rpc_resp pointer.

Also eventually the rpc would use the new slot without making
sure it is free by calling nfsd41_cb_setup_sequence().

This problem was introduced by a 4.1 protocol addition patch:
	[0421b5c5] nfsd41: Backchannel: Implement cb_recall over NFSv4.1

Which was overlooking the possibility of an RPC callback retries.
For not-4.1 case redoing the _prepare is harmless.

We must create the server before we can call init_socks or check the
number of threads.

Symptoms were a NULL pointer dereference in nfsd_svc().  Problem
identified by Jeff Layton.

Also fix a minor cleanup-on-error case in nfsd_startup().

A regression of building without CONFIG_HW_CONSOLE was introduced with
commit b45cfba4 (vt,console,kdb:
implement atomic console enter/leave functions).

ERROR: "con_debug_enter" [drivers/serial/kgdboc.ko] undefined!
ERROR: "vc_cons" [drivers/serial/kgdboc.ko] undefined!
ERROR: "fg_console" [drivers/serial/kgdboc.ko] undefined!
ERROR: "con_debug_leave" [drivers/serial/kgdboc.ko] undefined!

When there is no HW console the con_debug_enter and con_debug_leave
functions should have no code.
