526bbe81de qcacmn: Handle frag based ops based on rx_Desc_pool flag
Rx desc pool have a flag to identify whether frag or nbuf
operation needs to be performed for alloc, map, prep and
free buffer for monitor dest buffer.

This flag will be set only for mon destination desc pool,
if RX_MON_MEM_FRAG feature is enabled.
In all other case, It will be set to Zero and default nbuf
operation will be taken.
This flag get initialized at the time of pdev rx_desc_pool
initialization and gets reset while pdev deinit.

Mon destination buffer will have support for frag if
RX_MON_MEM_FRAG flag is set.

4a28f4483d qcacmn: Add sanity check for qdf_nbuf_put_tail
In DP while handling ppdu stats, we call qdf_nbuf_put_tail
and proceed with updating the nbuf data whithout a check on
the return status of qdf_nbuf_put_tail.

If the qdf_nbuf_put_tail API failed, would free the nbuf
and subsequent updates to the nbuf would result in use
after free, which is resulting in memory corruption.

Add check to verify the return status of qdf_nbuf_put_tail
and proceed accordingly.

Also while updating the ppdu stats, ensure the num of users
of ppdu is checked against the max number of users defined.

e919b20a34 qcacmn: Replenish last entry in monitor status ring
In current monitor status ring implementation,
on pdev_attach, (srng->num_entires – 1) entries
(to keep one entry slot between hp and tp)
are replenished and last entry is not replenished to HW.

With qcn9000 monitor mode HW enhancements, status and destination ring
can be made lock-stepped.
for qcn9000 lock step is achieved by making monitor status ring
follow the monitor destination reap for a PPDU

However in existing flow during attach monitor status replenish logic
do not fill last entry but is filled up during first subsequent reap.
for first ppdu, i.e. after reaping destination ring,
when status ring is reaped, as first entry (hp = srng->num_entires – 1)
in status ring is NULL, so lock-stepping is not achieved.

To address this issue for qcn9000 as well as HK:
	a. Replenish last entry in monitor status ring during attach
	b. Modify src srng peek API to peek it from hp+1 entry
	c. Introduce new HAL API get cur desc and move next
	d. Remove WAR to skip status ring entries if DMA is not done
