    Fix memory handling of 'call' in ovirt_rest_call_async() calls
    
    ovirt_rest_call_async() will end up calling rest_proxy_call_async()
    which takes a reference on its RestProxyCall argument so we can
    drop ours after calling ovirt_rest_call_async()
    This fixes a memory leak reported by valgrind.
