Do not invalidate EAP session 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 an EAP session entry, so avoid flushing the
cached session when only these parameters are changed. This is mainly to
allow forced roaming or network selection changes without causing fast
reauthentication to be disabled if the changes are done during RSN
association that used EAP.
