perf/x86/amd: Set the size of event map array to PERF_COUNT_HW_MAX

The entry for PERF_COUNT_HW_REF_CPU_CYCLES is not used on AMD, but is
referenced by filter_events() which expects undefined events to have a
value of 0.

Found via KASAN:

  UBSAN: Undefined behaviour in arch/x86/events/amd/core.c:132:30
  index 9 is out of range for type 'u64 [9]'
  UBSAN: Undefined behaviour in arch/x86/events/amd/core.c:132:9
