[ Upstream commit e7920b3e9d9f5470d5ff7d883e72a47addc0a137 ]

There some macros are unused and cause gcc warning. Remove them.

  fs/nilfs2/segment.c:137:0: warning: macro "nilfs_cnt32_gt" is not used [-Wunused-macros]
  fs/nilfs2/segment.c:144:0: warning: macro "nilfs_cnt32_le" is not used [-Wunused-macros]
  fs/nilfs2/segment.c:143:0: warning: macro "nilfs_cnt32_lt" is not used [-Wunused-macros]
