Update PMK in wpa_sm when roam+auth event indicated with authorized flag

Browse source 
Currently, the PMK used by the driver is not updated to wpa_sm when
roaming is completed by the driver with the cached PMKSA and the
roam+auth event is indicated with the authorized flag.

To fix this, identify the PMKSA entry from the PMKID sent in
Reassociation Request frame and update the correct PMK to wpa_sm from
the PMKSA entry.
