Ryusuke Konishi 973bec34bf nilfs2: fix sync silent failure
As of 32a88aa1, __sync_filesystem() will return 0 if s_bdi is not set.
And nilfs does not set s_bdi anywhere.  I noticed this problem by the
warning introduced by the recent commit 5129a469 ("Catch filesystem
lacking s_bdi").

 WARNING: at fs/super.c:959 vfs_kern_mount+0xc5/0x14e()

This ensures to set s_bdi for nilfs and fixes the sync silent failure.
