nbd: convert to use qio_channel_yield
In the client, read the reply headers from a coroutine, switching the
read side between the "read header" coroutine and the I/O coroutine that
reads the body of the reply.
In the server, if the server can read more requests it will create a new
"read request" coroutine as soon as a request has been read. Otherwise,
the new coroutine is created in nbd_request_put.
