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.
