```

## Steps to reproduce
1. Login with an admin (or someone who can create spaces)
2. Create a new space.
3. Add a couple of files in the space

## Expected behavior
No warning should appear.

## Actual behavior
Data race warning appears.

## Setup
Please describe how you started the server and provide a list of relevant environment variables or configuration files.

```console
OCIS_XXX=somevalue
OCIS_YYY=somevalue
PROXY_XXX=somevalue
```

## Additional context
Add any other context about the problem here.

Build oCIS with race detection and reproduce the warning while creating a new space. Start in vendor/github.com/owncloud/reva/v2/pkg/storage/utils/decomposedfs/node/permissions.go at AddPermissions, then inspect the concurrent calls from Decomposedfs.ListFolder in decomposedfs.go. Done means the creation flow no longer reports this data race under the race detector.
