wifi: rtw89: correct drop logic for malformed AMPDU frames

In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw89: correct drop logic for malformed AMPDU frames

The previous commit aims to fix issue caused by malformed AMPDU frames.
But the drop logic fails to deal with the first AMPDU packet paired with
certain range of sequence number, and leads to unexpected packet drop.
It is more likely to encounter this failure when there are busy traffic
during rekey process and could lead to disconnection from the AP.
Fix this by adding a initial state judgement and only reset status
during pairwise rekey.
