nilfs2: use mark_buffer_dirty to mark btnode or meta data dirty
This replaces nilfs_mdt_mark_buffer_dirty and nilfs_btnode_mark_dirty macros with mark_buffer_dirty and gets rid of nilfs_mark_buffer_dirty, an own mark buffer dirty function. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
