don't bother with propagate_mnt() unless the target is shared

commit 0b1b901b5a98bb36943d10820efc796f7cd45ff3 upstream.

If the dest_mnt is not shared, propagate_mnt() does nothing -
there's no mounts to propagate to and thus no copies to create.
Might as well don't bother calling it in that case.
