from firmware
2. Set the default pktlog buffer size to 10MB.

Support Monitor Mode for QCA6390 as RXDMA1 block is
now removed.
1. Monitor buffers are now received on rxdma_err_dst_ring
2. RXDMA1 monitor status ring is moved to RXDMA0 monitor
status ring
3. Msdu link descriptors are now returned to WBM descriptor
release ring.
4. Reap the Monitor buffers and return it to SW Refill ring.
5. Use the same rx descriptor pool for regular and monitor data.

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.
