[PATCH spice-gtk 2/5] giopipe: input return 0 and no error when peer is already closed

[marcandre.lureau@xxxxxxxxxx]

From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>

The peer stream may be closed, but may have failed to close self,
because it has pending operations. In this case indicate EOS on read
rather than returning an error. self will be close eventually on
dispose.
