nilfs2: add sufile function that can modify multiple segment usages
This is a preparation for the later cleanup patch ("nilfs2: remove list of freeing segments"). This adds nilfs_sufile_updatev() to sufile, which can modify multiple segment usages at a time. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
