Subject: [PATCH 5.16 0259/1017] f2fs: fix to enable ATGC correctly via gc_idle sysfs interface

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

[ Upstream commit 7d19e3dab0002e527052b0aaf986e8c32e5537bf ]

It needs to assign sbi->gc_mode with GC_IDLE_AT rather than GC_AT when
user tries to enable ATGC via gc_idle sysfs interface, fix it.
