[GIT PULL] target fixes for v3.16-rc3

[Nicholas A. Bellinger]

Hi Linus,

Here are the target-pending fixes for v3.16-rc3.  Please go ahead and
pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master

Mostly minor fixes this time around.  The highlights include:

  - iscsi-target CHAP authentication fixes to enforce explicit key values
    (Tejas Vaykole + rahul.rane)
  - Fix a long-standing OOPs in target-core when a alua configfs attribute
    is accessed after port symlink has been removed.  (Sebastian Herbszt)
  - Fix a v3.10.y iscsi-target regression causing the login reject status
    class/detail to be ignored (Christoph Vu-Brugier)
  - Fix a v3.10.y iscsi-target regression to avoid rejecting an existing ITT
    during Data-Out when data-direction is wrong (Santosh Kulkarni + Arshad Hussain)
  - Fix a iscsi-target related shutdown deadlock on UP kernels (Mikulas Patocka) 
  - Fix a v3.16-rc1 build issue with vhost-scsi + !CONFIG_NET (MST)

Thank you,

--nab
