Fix JFFS2 sync silent failure
JFFS2 does not appear to set s_bdi anywhere. And as of 32a88aa1,
__sync_filesystem() will return 0 if s_bdi is not set. As a result,
sync_fs() is never called for jffs2 and whatever remains in the wbuf
will not make it to the device.
Fix that up by assigning the mtd bdi.
