[PATCH AUTOSEL 4.19 104/237] f2fs: fix to spread clear_cold_data()

From: Chao Yu <yuchao0@huawei.com>

[ Upstream commit 2baf07818549c8bb8d7b3437e889b86eab56d38e ]

We need to drop PG_checked flag on page as well when we clear PG_uptodate
flag, in order to avoid treating the page as GCing one later.
