selftests: kvm/x86: Fix the warning in pmu_event_filter_test.c
The following warning appears when executing
make -C tools/testing/selftests/kvm
x86_64/pmu_event_filter_test.c: In function 'vcpu_supports_intel_br_retired':
x86_64/pmu_event_filter_test.c:241:28: warning: variable 'cpuid' set but not used [-Wunused-but-set-variable]
241 | struct kvm_cpuid2 *cpuid;
| ^~~~~
x86_64/pmu_event_filter_test.c: In function 'vcpu_supports_amd_zen_br_retired':
x86_64/pmu_event_filter_test.c:258:28: warning: variable 'cpuid' set but not used [-Wunused-but-set-variable]
258 | struct kvm_cpuid2 *cpuid;
| ^~~~~
Just delete the unused variables to stay away from warnings.
