Do not prepare skipped disks

When autodiscovering disks, disks can be skipped if either they are
removable, or if they have partitions on them. Skipped actions have no
'rc' attribute, though, so the 'ceph prepare' conditional fails unless
we first check to ensure that the results were not skipped before
checking the return value.
