f2fs: compress: use more readable atomic_t type for {cic,dic}.ref
refcount_t type variable should never be less than one, so it's a little bit hard to understand when we use it to indicate pending compressed page count, let's change to use atomic_t for better readability. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
