target: Send UA when changing LUN inventory
When changind the LUN inventory via core_enable_device_list_for_node() or core_disable_device_list_for_node() a REPORTED LUNS DATA HAS CHANGED UA should be send. (Convert to target_luns_data_has_changed helper usage - hch) Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
