[GIT PULL] SCSI fixes for 4.14-rc2

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

Eight mostly minor fixes for recently discovered issues 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:

Dave Carroll (1):
      scsi: aacraid: Fix 2T+ drives on SmartIOC-2000

Guilherme G. Piccoli (1):
      scsi: aacraid: Add a small delay after IOP reset

Hannes Reinecke (2):
      scsi: scsi_transport_fc: Also check for NOTPRESENT in fc_remote_port_add()
      scsi: scsi_transport_fc: set scsi_target_id upon rescan

Martin Wilck (1):
      scsi: ILLEGAL REQUEST + ASC==27 => target failure

Nikola Pajkovsky (1):
      scsi: aacraid: error: testing array offset 'bus' after use

Stefano Brivio (1):
      scsi: lpfc: Don't return internal MBXERR_ERROR code from probe function

Xin Long (1):
      scsi: scsi_transport_iscsi: fix the issue that iscsi_if_rx doesn't parse nlmsg properly
