With a little simple math we don't need another struct array to find the completion structs, so we can remove the ionic_cq_info altogether. This doesn't really save anything in the ionic_cq since it gets padded out to the cacheline, but it does remove the parallel array allocation of 8 * num_descriptors, or about 8 Kbytes per queue in a default configuration.
