Pull SCSI fixes from James Bottomley:
 "Eight mostly minor fixes for recently discovered issues in drivers"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: ILLEGAL REQUEST + ASC==27 => target failure
  scsi: aacraid: Add a small delay after IOP reset
  scsi: scsi_transport_fc: Also check for NOTPRESENT in fc_remote_port_add()
  scsi: scsi_transport_fc: set scsi_target_id upon rescan
  scsi: scsi_transport_iscsi: fix the issue that iscsi_if_rx doesn't parse nlmsg properly
  scsi: aacraid: error: testing array offset 'bus' after use
  scsi: lpfc: Don't return internal MBXERR_ERROR code from probe function
  scsi: aacraid: Fix 2T+ drives on SmartIOC-2000
