scsi: Don't abort scsi_scan due to unexpected response

    Orabug: 27072286

    During a scan for new LUNs, if an array misconfiguration results in
    an error (non-configured LUNs exist in the middle), this terminates the
    scsi scan:

     sd 12:0:0:0: Unexpected response from lun 1 while scanning, scan aborted

    This patch allows the scsi scan to continue, and prints this warning:

     sd 12:0:0:0: Unexpected response from lun 1 while scanning,
                   ignoring device
