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.

Currently data in "pl_tgt_hdr" is used directly from firmware without
any length check which may cause buffer over-read.
To address this issue add length check before accessing data offset

of inconsisten nbuf. Assert if fails.

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.
To address this issue, protect the pktlog buffer access using spinlock.

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

Implement iwpriv pktlog command to clear pktlog buffer.
This command is effective only if pktlog disable is issued previously.
This command needs one argument.
Command to use this feature : iwpriv wlan0 pktlog 4
