perf/x86/intel: Fix rtm_abort_event encoding on Ice Lake

commit 46b72e1bf4 upstream.

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.
