Pull SCSI target fixes from Nicholas Bellinger:
 "This series is larger than what I'd normally be conformable with
  sending for a -rc5 PULL request..

  However, the bulk of the series is localized to qla2xxx target
  specific fixes that address a number of real-world correctness issues,
  that have been outstanding on the list for ~6 weeks now.  They where
  submitted + verified + acked by the HW LLD vendor, contributed by a
  major production customer of the code, and are marked for v3.18.y
  stable code.

  That said, I don't see a good reason to wait another month to get
  these fixes into mainline.

  Beyond the qla2xx specific fixes, this series also includes:

   - bugfix for a long standing use-after-free in iscsi-target during
     TPG shutdown + demo-mode sessions.

   - bugfix for a >= v4.0 regression OOPs in iscsi-target during a
     iscsi_start_kthreads() failure.

   - bugfix for a >= v4.0 regression hang in iscsi-target for iser
     explicit session/connection logout.

   - bugfix for a iser-target bug where a early CMA REJECTED status
     during login triggers a NULL pointer dereference OOPs.

   - bugfixes for a handful of v4.2-rc1 specific regressions related to
     the larger set of recent backend configfs attribute changes.

  A big thanks to QLogic + Pure Storage for the qla2xxx target bugfixes"
