In all cases *except* iSCSI the get_fabric_name() string matches fabric_ops.name. Both fabric_ops.get_fabric_name() and fabric_ops.name are user facing, with the former being used for PR/ALUA state and the latter for configFS (config/target/$name), so we unfortunately need to keep both strings around for now. Replace the useless .get_fabric_name() accessor function with a const string fabric_name member variable.

All other fabric modules rely on .fabric_name matching and can drop the duplicate string.
