remote: Fix memory leak in remoteConnectGetAllDomainStats

The remote call actually doesn't free the arguments array so we leak
memory in case a domain list is specified. As the remote domain list
array consists only of stolen pointers from the actual domain objects
it's sufficient just to free the array.
