Review Comment:
When the add failed, it is to restore the quota usage.
If there was no update before, there is no need to update when it failed.
```
updateCountNoQuotaCheck(existing, pos, counts.negation());
```

> Calculating quota usage is primarily used to update directories labeled with
> the DirectoryWithQuotaFeature. When there is no valid
> DirectoryWithQuotaFeature in the paths of src and dst (excluding the root
> directory), the quota should not be calculated in rename scenarios:
> 1. rename1 does not change the quota of the root directory, so neither src
> nor dst contains DirectoryWithQuotaFeature (excluding the root directory).
> The operation of calculating quota should be skipped.
> 2. In the scenario of overwriting, rename2 still needs to consider
> calculating quota, otherwise it will affect the quotaUsage value of the root
> directory.
