[Patch v3 05/13] KVM: selftests: Convert hyperv_features test to using KVM_X86_CPU_FEATURE()

Vipin Sharma

From: Vitaly Kuznetsov <vkuznets@redhat.com>

hyperv_features test needs to set certain CPUID bits in Hyper-V feature
leaves but instead of open coding this, common KVM_X86_CPU_FEATURE()
infrastructure can be used.
