ionic: remove the cq_info to save more memory

Browse source 
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.
