nbd/client: Pass mode through to nbd_send_request
Once the 64-bit headers extension is enabled, the data layout we send over the wire for a client request depends on the mode negotiated with the server. Rather than adding a parameter to nbd_send_request, we can add a member to struct NBDRequest, since it already does not reflect on-wire format. Some callers initialize it directly; many others rely on a common initialization point during nbd_co_send_request(). At this point, there is no semantic change.
