only CCB type but also extra flags- one of which can be "position

In other changes: Add in a SA_QUIRK_NO_CPAGE quirk so that it's possible

Also do a couple of printout cleanups.
As per some discussion on FreeBSD-scsi, skip doing tape flushing
if we're reading tape logical block location (MTIOCRDSPOS).
