f2fs: fix defined but not used build warnings

Fix build warnings in f2fs when CONFIG_PROC_FS is not enabled
by marking the unused functions as __maybe_unused.

../fs/f2fs/sysfs.c:519:12: warning: 'segment_info_seq_show' defined but not used [-Wunused-function]
../fs/f2fs/sysfs.c:546:12: warning: 'segment_bits_seq_show' defined but not used [-Wunused-function]
../fs/f2fs/sysfs.c:570:12: warning: 'iostat_info_seq_show' defined but not used [-Wunused-function]
