libbb/loop: don't try to re-use existing loop device
loopinfo.lo_file_name is not enough to uniquely identify a file on a system with multiple mount namespaces. We could conceivably change this to dedup on (lo_rdevice, lo_inode), but, as the comment above the deleted code notes, this whole approach of reusing devices is racy anyway, so it seems better to stop doing it entirely.
