From: Nicholas Bellinger <n...@linux-iscsi.org>
This patch fixes a possible scsi_host reference leak in qlt_lport_register(),
when a non zero return from the passed (*callback) does not call drop the
local reference via scsi_host_put() before returning.
This currently does not effect existing tcm_qla2xxx code as the passed callback
will never fail, but fix this up regardless for future code.
