target: Fix regression allowing unconfigured devices to fabric port link
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:
commit 0fd97ccf45be26fb01b3a412f1f6c6b5044b2f16
Author: 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 commit 0fd97ccf code.
