Hannes Reinecke 80c716fad8 scsi: scsi_dh_alua: skip RTPG for devices only supporting active/optimized
For hardware only supporting active/optimized there's no point in ever
re-issuing RTPG as the only new state we can possibly read is
active/optimized.  This avoid spurious errors during path failover on
such arrays.
