wifi: rtw89: wow: add reason codes for disassociation in WoWLAN mode

Some APs disconnect clients by sending a Disassociation frame
rather than a Deauthentication frame. Since these frames use
different reason codes in WoWLAN mode, this commit adds support
for handling Disassociation to prevent missed disconnection events.
