ionic: Re-arrange ionic_intr_info struct for cache perf

dim_coal_hw is accessed in the hotpath along with other values
from the first cacheline of ionic_intr_info. So, re-arrange
the structure so the hot path variables are on the first
cacheline.

Before:

struct ionic_intr_info {
	char                       name[32];             /*     0    32 */
	unsigned int               index;                /*    32     4 */
	unsigned int               vector;               /*    36     4 */
	u64                        rearm_count;          /*    40     8 */
	unsigned int               cpu;                  /*    48     4 */

	/* XXX 4 bytes hole, try to pack */

	cpumask_t                  affinity_mask;        /*    56  1024 */
	/* --- cacheline 16 boundary (1024 bytes) was 56 bytes ago --- */
	u32                        dim_coal_hw;          /*  1080     4 */

	/* size: 1088, cachelines: 17, members: 7 */
	/* sum members: 1080, holes: 1, sum holes: 4 */
	/* padding: 4 */
};

After:

struct ionic_intr_info {
	char                       name[32];             /*     0    32 */
	u64                        rearm_count;          /*    32     8 */
	unsigned int               index;                /*    40     4 */
	unsigned int               vector;               /*    44     4 */
	unsigned int               cpu;                  /*    48     4 */
	u32                        dim_coal_hw;          /*    52     4 */
	cpumask_t                  affinity_mask;        /*    56  1024 */

	/* size: 1080, cachelines: 17, members: 7 */
	/* last cacheline: 56 bytes */
};
