Protect pktlog funcitonality under given mutex to avoid possible
race condition between pktlog_release/pktlog_open and pktlogmod_exit.
Also call pktlogmod_exit before calling wdi_event_detach to avoid
accessing freed memory in pktlog release.

The packet logs show in console logs which are redundant.
Change the log level from qdf_print to qdf_debug to avoid
excessive logging.

Per the Linux Kernel coding style, as enforced by the kernel
checkpatch script, pointers should not be explicitly compared to
NULL. Therefore within utils replace any such comparisons with logical
operations performed on the pointer itself.

1. Enable CE5 and allow it to service
pktlog messages from the firmware.
2. Register full pktlog callback handlers
for handling sw_events and full tx pktlog.

If user tries to enable pktlog multiple times, pktlog enable
fails as the pktlog is already enabled.
while returning failure, current pktlog state is not updated
to PKTLOG_OPR_NOT_IN_PROGRESS in pktlog_enable api.
Now if user tries to get pktlog using cat command driver
returns resource busy from pktlog_enable as the current
pktlog state is not set to PKTLOG_OPR_NOT_IN_PROGRESS.
To address this issue, set the current pktlog state to
PKTLOG_OPR_NOT_IN_PROGRESS in case of failure.

If log state 1, 2, 0, 1 are set serially, log state 2 can't be set
successfully, while log state 1 is set to wdi twice, which results
in two same pointers in doubly linked list txrx_pdev->wdi_event_list
and causes dead loop.
Update pl_info->log_stat only when it is subscribed to wdi and sent
to firmware successfully.

There can be a race condition if the pktlog_buf inside pktlog APIs,
is accessed simultanously from two threads.
To prevent this use mutex in the caller functions of pktlog APIs.

There can be a race condition if two different threads use the
pkt log buffer at the same time. This issue can lead to Use-After-Free
of the packet log buffer.

Add infrastructure in pktlog utils to collect pktlogs as part
of bug report generation. As part of this when pktlog read command
is received on host:
1. disable pktlog,
2. read pktlog,
3. clear pktlog buffer,and
4. Retain pktlog initial state
