During GC, if segment type stored in SSA and SIT is inconsistent,
we set SBI_NEED_FSCK first and then stop checkpoint, this will
cause the following issues:
1. SBI_NEED_FSCK can not be set to flash truly because of checkpoint
has been stopped.
2. Will cause more EIO error because of CP_ERROR_FLAG is set in
f2fs_stop_checkpoint, this is not reasonable.
So we fix this error handling case by recording current victim segment
as invalid for gc.
