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 */
