"could not read quota" error messages

## Describe the bug

When starting oCIS from single binary the first time it clutters the console with error messages like
```
{"level":"error","service":"storage-users","pkg":"rgrpc","traceid":"00000000000000000000000000000000","error":"no data available","nodepath":"/data/ocis/base/storage/users/spaces/4c/510ada-c86b-4815-8820-42cdf82c3d51/nodes/4c/51/0a/da/-c86b-4815-8820-42cdf82c3d51","time":"2022-11-24T18:08:28.983827677+01:00","message":"could not read quota"}
```
a lot.

This is probably a pretty useless logging as this is expected.

It gives a bad impression to first-time starters I think, especially with the "no data available" part.

## Expected behavior
Just do not print this error message. Maybe make it a warning or debug level.
