Remove use of channels from p9.connState legacy transport.
- Remove sendDone, which currently does nothing whatsoever (errors sent to the
channel are completely unused). Instead, have request handlers log errors
they get from p9.send() inline.
- Replace recvOkay and recvDone with recvMu/recvIdle/recvShutdown. In addition
to being slightly clearer (IMO), this eliminates the p9.connState.service()
goroutine, significantly reducing the overhead involved in passing connection
receive access between goroutines (from buffered chan send/recv + unbuffered
chan send/recv to just a mutex unlock/lock).
