With the previous two fixes for the write / ioctl races:
  ALSA: seq: Don't allow resizing pool in use
  ALSA: seq: More protection for concurrent write and ioctl races
the cells aren't any longer in queues at the point calling
snd_seq_pool_done() in snd_seq_ioctl_set_client_pool().  Hence the
function call snd_seq_queue_client_leave_cells() can be dropped safely
from there.

This patch is an attempt for further hardening against races between
the concurrent write and ioctls.  The previous fix d15d662e
("ALSA: seq: Fix racy pool initializations") covered the race of the
pool initialization at writer and the pool resize ioctl by the
client->ioctl_mutex (CVE-2018-1000004).  However, basically this mutex
should be applied more widely to the whole write operation for
avoiding the unexpected pool operations by another thread.

The only change outside snd_seq_write() is the additional mutex
argument to helper functions, so that we can unlock / relock the given
mutex temporarily during schedule() call for blocking write.

This is a fix for a (sort of) fallout in the recent commit
d15d662e ("ALSA: seq: Fix racy pool initializations") for
CVE-2018-1000004.
As the pool resize deletes the existing cells, it may lead to a race
when another thread is writing concurrently, eventually resulting a
UAF.

A simple workaround is not to allow the pool resizing when the pool is
in use.  It's an invalid behavior in anyway.

This reverts commit 48282969 which
caused the following issues:

1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.

The following dmesg errors can be observed:
thinkpad_acpi: EC reports that Thermal Table has changed
rmi4_smbus 7-002c: failed to get SMBus version number!
rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask.

rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts!
psmouse: probe of serio3 failed with error -1

2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.

Analysis form Richard Schütz:

"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae8195 ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."

The affected devices often show:

i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers
i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK

If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
