cxgb4: Try and provide an RDMA CIQ per cpu
To allow for better scalability on systems with large core counts, we
will try and allocate enough RDMA Concentrator IQs and MSI/X vectors as
we have cores. If we cannot get enough MSI/X vectors, fall back to the
minimum required: 1 per adapter rx channel.
Also clean up cxgb_enable_msix() to make it readable and correct a bug
where the vectors are not correctly assigned if the driver doesn't get
the full amount requested.
