wlan: qcacld: Fix to remove dropping of consecutive Deauth frame
In order to prevent rogue AP from pumping DEAUTH into STA, throttling
mechanism have been added to throttle the number of DEAUTHs allowed in
a given time. Since SA query process is used in case of PMF connection,
this check can be avoided.
This change set provides fix for skipping the DEAUTH count check for
PMF connection.
