The validation of iscsi session should be case insensitive

The validation of iscsi session should be case insensitive since IPv6
address is case insensitive. If the portal address are all lower cases,
and the address get from 'iscsiadm -m session' contain upper cases,
the validation of iscsi session will failed, the loop will be endless.
