rbd: fix up the layering warning message
A warning gets spewed for any image being probed, including parent
images. Set up a condition such that the warning message only gets
printed for the image being mapped, not any of its parents.
Also, I didn't like the way the warning ended up being so long.
Make it a terse warning instead. People experimenting with layering
will know what the message means.
