qcacmn: Fix out of sync OOM work counter

Currently OOM work counter is incremented when schedule_work
is called and counter is decremented when work is scheduled.
But there is possibility of OOM schedule_work is getting called
from tasklet context and worker thread context and resulting
only one time work execution but active work counter being
incremented twice. This scenario may result in OOM work going
out of sync and preventing suspend usecase.

Avoid this by incrementing the OOM active work count only when
work is getting added to global work queue and corresponding count
will be decremented when work handler gets executed.

qcacmn: Fix QDF documentation

The kernel-doc script identified a large number of documentation
issues in the QDF. A series of patches has already fixed many of the
issues, so fix most of the remaining ones.

Note that the QDF IPA abstraction still has issues, but it is under
rework, so not trying to clean it up until after the rework is
complete.

qcacmn: Properly abstract the Linux bottom half interfaces

When migrating to Linux Kernel v5.19 the following compilation error
was encountered:

i_qdf_defer.h:192:19: error: cast from 'qdf_defer_fn_t' (aka 'void (*)(void *)') to '__qdf_bh_fn_t' (aka 'void (*)(unsigned long)') converts to incompatible function type [-Werror,-Wcast-function-type]
tasklet_init(bh, (__qdf_bh_fn_t) func, (unsigned long)arg);

This revealed the fact that the QDF bottom half abstraction was not
cleanly implemented. The current implementation freely typecasts the
abstracted signature:
void (*func)(void *arg)
with the Linux-specific signature:
void (*func)(unsigned long arg)

This has worked in the past since a void * and and unsigned long are
the same size and hence could be freely converted from one to another.
However the Linux Kernel now supports Call Flow Integrity which
requires that the function signatures must always exactly match.

To address this issue rewrite the bottom half abstraction to use an
intermediate dispatching function, exactly like is already done for
the deferred work abstraction.

qcacmn: Use UNBOUND flag to create WMI RX workqueue

WMI RX workqueue is created with WQ_MEM_RECLAIM flag. When host receives
the WMI service ready event it queues the work. There is 50sec delay in
scheduling workqueue to process WMI service ready event. This results in
host timeout (timeout = 15sec) and wifi load failure. This cleans up the
host data structures related to data path. But work got scheduled after
50sec resulting in init path handling with inconsistent data structures.

Use workqueue UNBOUND flag to create WMI RX workqueue. Works queued to
unbound workqueues are implicitly HIGHPRI and dispatched to unbound
workers as soon as resources are available.
