crash scenario:
a. dp_tx_vdev_detach will reset the vdev of TX desc to NULL
by dp_tx_desc_flush.
b. in the meantime, if TX completion is coming and when all TX desc
is recycled, the pool will be freed if pool status is invalid before.
c. invalid TX desc accessing will happen in (a).
add TX desc pool lock protection in dp_tx_desc_flush.

Currently the cdp apis are given pdev/vdev/peer
handle as its arguments, which is directly
accessed in those APIs. This can cause a
race-condition in access of the respective
handles, if it has been deleted in parallel.
Hence as a part of cdp convergence, pass only
the pdev/vdev id or peer mac address, which will be
used to get the respective handles, and hence
avoiding the unwanted access of the handles, if
it has been deleted.

In the present scenario, in case of Multicast Enhancement when
the multicast packet is received the packet is converted to
unicast packet and send to list of clients in the hyfi table.
During conversion descriptors get allocated from ME pool
for each client and the Tx MSDU descriptor is send to HW
for transmit. On TX completion descriptors are freed and
added back to ME pool.
But if the HW enqueue is failed then the current TX descriptor
is freed and added back to ME pool. But the remaining descriptor
are neither retried nor freed thus resulting in Host Asserted
Crash.
So, adding a fix that if the HW enqueue is failed for ME packet,
free that descriptor and retry HW enqueuing for the remaining
descriptors.

offload case SW2TCL3 righ hp value will be updated by IPA

mode configuration is only possible through INI setting

pdev 'up' or 'down' status to DP module
2. Add pdev-status check in dp_rx_process_invalid_peer
3. Add pdev-status check in dp_tx_comp_handler to free

In some corner case, host has done Vdev destroy and TX desc flush
since there is pending outstanding TX data on this vdev, but later
FW/HW still indicate the TX completion to host and which likely
these TX completion get delayed, conflict happened due to same TX
Desc accessing.
To fix it:
(1) Only reset TX desc Vdev to NULL in dp_tx_vdev_detach().
(2) Do more enhancement in dp_tx_comp_handler() to avoid
invalid Vdev accessing.
(3) Do TX desc flush in dp_tx_pdev_detach().
