The coverity server found issue in gvir_stream_close function that
we ignore return values of g_input_stream_close and
g_output_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. We should try to close both streams even if
closing the first one will fails. We can propagate only one error
message.
