This issue is related to resatart/reconfigure AP.

When AP is restarted or reconfigured, wpa_supplilcant will use cached
PMKSA to do association to AP.
Because association failure does not report to cfg80211/wpa_supplicant,
wpa_supplicant will always use cached PMKSA to do assocaiton.
Connection can't be established under this way.
