Ensure that cv_end is equal to ibdev->num_comp_vectors for the NUMA node with the highest index. This patch improves spreading of RDMA channels over completion vectors and thereby improves performance, especially on systems with only a single NUMA node. This patch drops support for the comp_vector login parameter by ignoring the value of that parameter since I have not found a good way to combine support for that parameter and automatic spreading of RDMA channels over completion vectors.
