x86/cpufeature: Fix build bug caused by merge artifact with the removal of cpu_has_hypervisor
The 0-day build robot by Fengguang Wu reported a build failure: arch/x86/events//intel/cstate.c: In function 'cstate_pmu_init': arch/x86/events//intel/cstate.c:680:6: error: 'cpu_has_hypervisor' undeclared (first use in this function) ... which was caused by a merge mistake I made when applying the following patch: 0c9f3536cc71 ("x86/cpufeature: Remove cpu_has_hypervisor") apply the missing hunk as well.
