Subject: fs/nilfs2: remove some unused macros to tame gcc

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]
