rnbd-clt: don't free rsp in msg_open_conf for map scenario
For map scenario, rsp is freed in two places:
1. msg_open_conf frees rsp if rtrs_clt_request returns 0.
2. Otherwise, rsp is freed by the call sites of rtrs_clt_request.
Now, We'd like to control full lifecycle of rsp in rnbd_clt_map_device,
with that, it is feasible to pass rsp to rnbd_client_setup_device in
next commit.
For 1, it is possible to free rsp from the caller of send_usr_msg
because of the synchronization of iu->comp.wait. And we put iu later
in rnbd_clt_map_device to ensure order of release rsp and iu.
