f2fs: don't split checkpoint in fstrim
Now, we issue discard asynchronously in separated thread instead of in checkpoint, after that, we won't encounter long latency in checkpoint due to huge number of synchronous discard command handling, so, we don't need to split checkpoint to do trim in batch, merge it and obsolete related sysfs entry.
