    gthreadedresolver: fix hang on g_thread_pool_push() failure
    
    In resolve_sync function in gthreadedresolver.c, if g_thread_pool_push
    fails due to thread creation failure, we are just simply appending the
    data to the queue of work to do. After the failure, we might wait
    indefinitely in g_cond_wait. In case of g_thread_pool_push failure,
    propagate the error so that this function does not blocks forever in
    case of failure.
