tcp: Make error handling in tcp_usr_send() more consistent

- Free the input mbuf in a single place instead of in every error path.
- Handle PRUS_NOTREADY consistently.
- Flush the socket's send buffer if an implicit connect fails.  At that
  point the mbuf has already been enqueued but we don't want to keep it
  in the send buffer.
