qcacmn: Remove call to qdf_exit_thread()

Since Linux Kernel commit 63706172f332 ("kthreads: rework
kthread_stop()"), made in 2009 in Linux Kernel v2.6.31-rc1, it has not
been necessary for kernel threads to call do_exit(). Since we do not
support kernels earlier than that, remove the call to
qdf_exit_thread(), the abstraction function for do_exit().

See Change-Id I22f27692fa8766df080630b9b0640c259285557c for more
information on why this call is being removed.

qcacmn: Add API to configure scheduler watchdog timeout

The scheduler watchdog timeout is currently fixed at 10secs.
There are few customer use cases, where the CPU is busy for
sometime and the scheduler message processing is taking longer than
the coinfigured watchdog timeout value.

Add a new API to be able to configure this value different than the
default as per the requirement.

qcacmn: Remove qdf_flex_mem_release()

Due to a limitation in the memory leak detection logic when qdf_flex_mem
was written, qdf_flex_mem_release() was necessary to free any
dynamically allocated memory in the qdf_flex_mem_pool during certain
points in the WLAN driver lifecycle. This was done to avoid flagging any
dynamically allocated qdf_flex_mem_segments as false positive leaks
when the memory domains were changed and leak checking was performed.
With the introduction of qdf_talloc(), this workaround is no longer
required. Replace the calls to qdf_mem_malloc/free with qdf_talloc/free,
and remove qdf_flex_mem_release() altogether.

qcacmn: Wait for scheduler buffers before we panic

The scheduler can run out of buffers and we panic
whenever this happens. However in the older code
we wait until the failure count of getting scheduler
buffers reaches a defined limit, thus making buffers
available in due time and the panic was seen in rare cases,
where failure count was exceeding the defined limit.

With the qdf_flex_mem supprt added for scheduler, the
wait to panic, when the failure count was removed and
we panic when the first failure to get scheduler buffer
is reached. This change adds to wait until the failure
count reaches the limit and then panic.

Currently, the scheduler thread keeps a large, pre-allocated array of
messages for use in message posting. The vast majority of the time,
however, the scheduler thread has zero or one messages pending in the
queue. This leads to a huge memory overhead for nominal driver
operation.

hybrid static/dynamic approach.
