This patch fixes a v3.8-rc1 regression bug where an unconfigured se_device was incorrectly allowed to perform a fabric port-link. This bug was introduced in commit: commit0fd97ccf45Author: Christoph Hellwig <hch@infradead.org> Date: Mon Oct 8 00:03:19 2012 -0400 target: kill struct se_subsystem_dev which ended up dropping the original se_subsystem_dev->se_dev_ptr check preventing this from happening with pre commit0fd97ccfcode.
