nilfs2: use root object to get ifile
This rewrites functions using ifile so that they get ifile from nilfs_root object, and will remove sbi->s_ifile. Some functions that don't know the root object are extended to receive it from caller. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
