Avoid logging EOF and ErrClosedPipe errors.
...
smux Stream.WriteTo may return io.EOF, which breaks the contract of
io.Copy that says it should not return io.EOF. smux.Stream doesn't have
a unidirectional shutdown, so we always end up slamming it shut in both
directions and leave the other direction with a broken pipe.

Sending just 4 bytes and relying on the convid for the remaining bytes
doesn't work for empty polling requests. Could probably just eliminate
the convid and make it a static constant before feeding to KCP.
