ionic: remove desc, sg_desc and cmb_desc from desc_info

Browse source 
Remove the struct pointers from desc_info to use less space.
Instead of pointers in every desc_info to its descriptor,
we can use the queue descriptor index to find the individual
desc, desc_info, and sgl structs in their parallel arrays.

   struct ionic_desc_info
	Before:  /* size: 496, cachelines: 8, members: 10 */
	After:   /* size: 472, cachelines: 8, members: 7 */
