Fail if 'rbd rm' fails - most probably it'd fail with "image still has watchers" and in that case it's a bug in the kernel client which we do want to notice. Also nuke the trap-based error handling - cleanup() is half-baked and not really necessary here. Signed-off-by: Ilya Dryomov <ilya.dryomov@inktank.com>
