When orphan_file feature is enabled, ext4_orphan_cleanup() was always
walking through the orphan file looking for orphan inodes. This is
mostly harmless but for read-only filesystem it results in spurious
"orphan cleanup on readonly fs" message and in other cornercases it
could result in similar somewhat misleading messages. Skip orphan
cleanup if the orphan file is empty to avoid confusing messages.
