[PATCH 1/2] perf/x86/intel: Fix rtm_abort_event encoding on Ice Lake

From: Kan Liang <kan.liang@linux.intel.com>

According to the event list from icelake_core_v1.09.json, the encoding
of the RTM_RETIRED.ABORTED event on Ice Lake should be,
"EventCode": "0xc9",
"UMask": "0x04",
"EventName": "RTM_RETIRED.ABORTED",

Correct the wrong encoding.
