Subject: sdn: api: return null for rollback / lock endpoints

lock_sdn_config can return a boolean value, which will then in turn
get returned as data from the API calls. Since we hint type null here,
this leads to problems with the pve-api-client in rust. Fix the return
value for this API call by adding an explicit return statement.
