target: Add link_magic for fabric allow_link destination target_items
commit 0ff8754981261a80f4b77db2536dfea92c2d4539 upstream.
This patch adds [dev,lun]_link_magic value assignment + checks within generic
target_fabric_port_link() and target_fabric_mappedlun_link() code to ensure
destination config_item *target_item sent from configfs_symlink() ->
config_item_operations->allow_link() is the underlying se_device->dev_group
and se_lun->lun_group that we expect to symlink.
