qcacld-3.0: Fix logic to drop duplicate deauth/disassoc frames

In wma_is_pkt_drop_candidate the enum values used to check the
frame subtype is not proper and disassoc subtype is compared to
SIR_MAC_MGMT_DISASSOC instead of IEEE80211_FC0_SUBTYPE_DISASSOC.
Similar enum mismatch is present for deauth frame.

Also 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
WMA_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 rouge peer keep on sending rogue
deauth/disassoc frames and thus even if peer send valid deauth
peer will not get disconnected.

Fix this by using proper enum values to map the frame subtype.
Also update the rcvd time stamp only when the frame is allowed,
as this timestamp should be used to block the duplicate
frames for WMA_MGMT_FRAME_DETECT_DOS_TIMER ms.
