I think we'd better add condition here (under inode lock) to disallow enabling
verity on atomic/volatile inode, as we may fail to write merkle tree data due to
atomic/volatile inode's special writeback method.

We can get rid of dquot_initialize() here, since f2fs_file_open() ->
dquot_file_open() should has initialized quota entry previously, right?
