Do not clear PMKSA cache on all network block parameter changes

Browse Source 
The bssid and priority parameters in a network block do not have any
effect on the validity of a PMKSA cache entry, so avoid flushing the
PMKSA cache when only these parameters are changed. This is mainly
to allow forced roaming or network selection changes without causing
a disconnection if the changes are done during RSN association that
used EAP.
