Jouni Malinen 4158b80eef wlantest: Do not update RSC on replays
This changes wlantest behavior to mark CCMP/TKIP replays for more cases
in case a device is resetting its TSC. Previously, the RSC check got
cleared on the first marked replay and the following packets were not
marked as replays if they continued incrementing the PN even if that PN
was below the highest value received with this key at some point in the
past.
