[PATCH v2] perf test amd: Fix build failure with amd-ibs-via-core-pmu.c

[Ravi Bangoria]

Since amd-ibs-via-core-pmu.c was applied via Peter's tree, some of
the changes came via Arnaldo's tree did not reflect in this file,
which is causing build failures.

  arch/x86/tests/amd-ibs-via-core-pmu.c:47:25: error: ‘pmus’ undeclared
  (first use in this function)
     47 |         if (list_empty(&pmus))
        |                         ^~~~

     48 |                 perf_pmu__scan(NULL);
        |                 ^~~~~~~~~~~~~~
        |                 perf_pmus__scan
  arch/x86/tests/amd-ibs-via-core-pmu.c:50:19: error: implicit declaration
  of function ‘perf_pmu__find’; did you mean
  perf_pmus__find’? [-Werror=implicit-function-declaration]
     50 |         ibs_pmu = perf_pmu__find("ibs_op");
        |                   ^~~~~~~~~~~~~~
        |                   perf_pmus__find

Fix those.
