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.
