When building with W=1, we got one warning as belows:
drivers/net/wireless/ath/ath6kl/wmi.c:3509:6: warning: variable ‘ret’
set but not used [-Wunused-but-set-variable]

At the end of ath6kl_wmi_set_pvb_cmd, it is returned by 0 regardless of
return value of ath6kl_wmi_cmd_send.
This patch fixes return value from 0 to ret that has result of
ath6kl_wmi_cmd_send execution.

Firmware is running watchdog timer for tracking copy engine ring index
and write index. Whenever both indices are stuck at same location for
given duration, watchdog will be trigger to assert target. While
updating copy engine destination ring write index, driver ensures that
write index will not be same as read index by finding delta between these
two indices (CE_RING_DELTA).

HTT target to host copy engine (CE5) is special case where ring buffers
will be reused and delta check is not applied while updating write index.
In rare scenario, whenever CE5 ring is full, both indices will be referring
same location and this is causing CE ring stuck issue as explained
above. This issue is originally reported on IPQ4019 during long hour stress
testing and during veriwave max clients testsuites. The same issue is
also observed in other chips as well. Fix this by ensuring that write
index is one less than read index which means that full ring is
available for receiving data.

Ignore processing further in SWBA event scheduled for a vif, if mac80211
has marked the particular vif for stop beaconing and brought the vdev
down in 'ath10k_control_beaconing'. This should potentially avoid ath10k
warning/error messages while running continuous wifi down/up with max
number of vaps configured. Found this change during code walk through
and going through other beacon configuration related functions in ath10k
