UBIFS: do not write orphans back
Orphan inodes are deleted inodes which will disappear after FS re-mount. There is not need to write orphan inodes back, because they are not needed on the flash media. So optimize orphans a little by not writing them back. Just mark them as clean, free the budget, and report success to VFS. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
