From: Chao Yu <chao@kernel.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.

Fixes: 093749e296e2 ("f2fs: support age threshold based garbage collection")
