f2fs: fix to clear CP_TRIMMED_FLAG
[ Upstream commit cd36d7a17f9da68be9aa67185ba3ad7969934a19 ]
Once CP_TRIMMED_FLAG is set, after a reboot, we will never issue discard
before LBA becomes invalid again, fix it by clearing the flag in
checkpoint without CP_TRIMMED reason.
Fixes: 1f43e2ad7bff ("f2fs: introduce CP_TRIMMED_FLAG to avoid unneeded discard")
