nilfs2: add barrier mount option
Nilfs enables write barriers by default and has "nobarrier" mount option to disable this feature. But it lacks the complementary option and has no way to re-enable the feature on remount. This adds "barrier" option to resolve this imbalance. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
