nilfs2: simplify nilfs_sufile_get_ncleansegs function
Previously, this function took an status code to return possible error codes. The ("nilfs2: add local variable to cache the number of clean segments") patch removed the possibility to return errors. So, this simplifies the function definition to make it directly return the number of clean segments. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
