[GIT PULL] SCSI fixes for 7.0-rc3

[James Bottomley <James.Bottomley@HansenPartnership.com>]

The one core change is a re-roll of the tag allocation fix from the
last pull request that uses the correct goto to unroll all the
allocations.  The remianing fixes are all small ones in drivers.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Junxiao Bi (1):
      scsi: core: Fix error handling for scsi_alloc_sdev()

Vladimir Riabchun (1):
      scsi: qla2xxx: Completely fix fcport double free

Wang Shuaiwei (1):
      scsi: ufs: core: Fix SError in ufshcd_rtc_work() during UFS
suspend

Xingui Yang (1):
      scsi: hisi_sas: Fix NULL pointer exception during user_scan()
