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.
