wifi: mac80211: ibss: read deauth reason_code after frame length check

Browse source

The function was reading reason_code from the frame before validating
that the frame is at least IEEE80211_DEAUTH_FRAME_LEN bytes long.

Move the reason_code read to after the length check so the field is
guaranteed to be present before it is accessed.
