rbd CLI tool was rewritten in infernalis, making argument handling
more strict.  While rbd showmapped might have accepted -p and --image
in 0.80.7, I don't think it ever did any filtering - they were simply
ignored.  If you do "rbd showmapped" without any options, you should
get the same result in 10.2.4.

Thanks,
