ubifs: Check ubifs_wbuf_sync() return code

Browse source

commit aac17948a7 upstream.

If ubifs_wbuf_sync() fails we must not write a master node with the
dirty marker cleared.
Otherwise it is possible that in case of an IO error while syncing we
mark the filesystem as clean and UBIFS refuses to recover upon next
mount.
