f2fs: code cleanup for scan_nat_page() and build_free_nids()
This patch does two cleanups: 1. remove unused variable "fcnt" in build_free_nids(). 2. make scan_nat_page() as void type and remove useless variable "fcnt". Signed-off-by: Haicheng Li <haicheng.li@linux.intel.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
