scsi: devinfo: add BLIST_RETRY_ITF for EMC Symmetrix
EMC Symmetrix returns 'internal target error' for a variety of conditions, most of which will be transient. So we should always retry it, even with failfast set. Otherwise we'd get spurious path flaps with multipath. Signed-off-by: Martin Wilck <mwilck@suse.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
