Rate limit transition validation for RC QPs currently relies on the IB core qp_state_table. Add a driver-level helper to validate the rate limit attribute directly during QP modify, ensuring it is only accepted for RC QPs in INIT->RTR, RTR->RTS and RTS->RTS transitions. This makes the driver responsible for rate limit validation and prepares for a follow-up IB core change that delegates IB_QP_RATE_LIMIT and all future non-standard modify attributes handling to individual vendor drivers.
