wpa_supplicant: Improve PSK mismatch detection

As the comment in wpa_supplicant_event_disassoc_finish() says,
mac80211-based drivers use the WLAN_REASON_DISASSOC_DUE_TO_INACTIVITY
reason code in locally generated disconnection events for cases where
the AP does not reply anymore. This case does not indicate that the PSK
is wrong.
