nilfs2: replace barriers with explicit flush / FUA usage
Switch to the WRITE_FLUSH_FUA flag for log writes, remove the EOPNOTSUPP
detection for barriers and stop setting the barrier flag for discards.
tj: nilfs is now fixed to wait for discard completion. Updated this
patch accordingly and dropped warning about it.
