qcacld-2.0: Fix logic to drop duplicate deauth/disassoc frames

propagation from qcacld-3.0 to qcacld-2.0.

The frame received time is updated even when the frame was
dropped and thus the received time of the frame keeps on increasing.
Thus the condition to check if frame is allowed after
TLSHIM_MGMT_FRAME_DETECT_DOS_TIMER ms always fails if driver
continuously keep on getting the frames.

This can lead to dropping of valid deauth/disassoc frames in case
if RMF is enabled and some rogue peer keep on sending rogue
deauth/disassoc frames and thus even if peer send valid deauth
peer will not get disconnected.

Fix this by updating the rcvd time stamp only when the frame is
allowed, as this timestamp should be used to block the duplicate
frames for TLSHIM_MGMT_FRAME_DETECT_DOS_TIMER ms.
