perf mem: Fix display of data source snoop indication

'perf mem report' doesn't display the data source snoop indication correctly.

In the kernel API the definition is:

#define PERF_MEM_SNOOP_NONE 0x02 /* no snoop */
#define PERF_MEM_SNOOP_HIT 0x04 /* snoop hit */
#define PERF_MEM_SNOOP_MISS 0x08 /* snoop miss */

but the table used by the perf tools exchanged "Hit" and "Miss":

"None",
"Miss",
"Hit",

Fix the table in perf.
