ionic: rearrange ionic_queue for better layout

A simple change to the struct ionic_queue layout removes some
unnecessary padding and saves us a cacheline in the struct
ionic_qcq layout.

    struct ionic_queue {
	Before: /* size: 256, cachelines: 4, members: 29 */
	After:  /* size: 192, cachelines: 3, members: 29 */

    struct ionic_qcq {
	Before: /* size: 2112, cachelines: 33, members: 23 */
	After:  /* size: 2048, cachelines: 32, members: 23 */
