http2: close client connections after receiving GOAWAY

Once a connection has received a GOAWAY from the server,
close it after the last outstanding request on the connection

We're lax about when we call ClientConn.closeConn, frequently
closing the underlying net.Conn multiple times. Stop propagating
errors on closing the net.Conn up through ClientConn.Close and
ClientConn.Shutdown, since these errors are likely to be caused
by double-closing the connection rather than a real fault.

Fixes golang/go#39752.
