Jack Wang 5e91eabf66 RDMA/rtrs-srv: Set minimal max_send_wr and max_recv_wr ... Currently rtrs when create_qp use a coarse numbers (bigger in general), which leads to hardware create more resources which only waste memory with no benefits. For max_send_wr, we don't really need alway max_qp_wr size when creating qp, reduce it to cq_size. For max_recv_wr, cq_size is enough. With the patch when sess_queue_depth=128, per session (2 paths) memory consumption reduced from 188 MB to 65MB When always_invalidate is enabled, we need send more wr, so treat it special.
