IB/srpt: Remove WARN_ON from srpt_cm_req_recv
The callers pass the pointer '&req' or 'private_data' to srpt_cm_req_recv(), and 'private_data' is initialized in srp_send_req(). 'sdev' is allocated and stored in srpt_add_one(). It's easy to show that sdev and req are always valid. So we remove unnecessary WARN_ON.
