cpukit/jffs2: Properly commit JFFS2 data
When unmounting a JFFS2 filesystem, any outstanding write buffers must
be flushed to disk. In some circumstances, these write buffers are
instantiated by a garbage collection pass and as such no inode number is
associated with it. Due to the way that JFFS2 processes these garbage
collection passes, a write buffer without any associated inodes will not
be flushed unless it is forced with jffs2_flush_wbuf_pad().
