qcacld-2.0: Drop same seq num auth frame only if retry bit is set
AP configured in WEP open type is sending auth frame with
same sequence number. DUT sends auth frame, first with auth
algo as shared key and then as open system. Since, AP sends
auth frame with same sequence number, DUT drops the frame
which results in authentication failure.
Fix is to drop auth frame with same sequence number only
if retry bit is set.
