[ws-daemon] Don't try to re-set same quota

[csweichel]

We must not set the CFS quota when that same quota is already in place. If we do so, we'll incur an error where there is none.

fixes #5326

How to review

1. Start a workspace
2. Verify that ws-daemon does not spew error messages to the tune of "cannot set CFS quota"
