nilfs2: call nilfs_error inside bmap routines
Some functions using nilfs bmap routines can wrongly return invalid argument error (i.e. -EINVAL) that bmap returns as an internal code for btree corruption. This fixes the issue by catching and converting the internal EINVAL to EIO and calling nilfs_error function inside bmap routines. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
