Subject: [PATCH 5.10 418/545] f2fs: dont set GC_FAILURE_PIN for background GC

From: Chao Yu <chao@...nel.org>

[ Upstream commit 642c0969916eaa4878cb74f36752108e590b0389 ]

So that it can reduce the possibility that file be unpinned forcely by
foreground GC due to .i_gc_failures[GC_FAILURE_PIN] exceeds threshold.
