[libvirt] [PATCH glib] gobject-stream: fix issue found by coverity

The coverity server found issue in gvir_stream_close function that we ignore return values of g_input_stream_close and g_outpu_stream_close, but we also ignore the error message and we assume that it's closed without error. Now we will check return values and also propagate the error message to the upper layers.
