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.
