[PATCH v2 071/144] KVM: selftests: Convert vmx_apic_access_test away from VCPU_ID

Sean Christopherson
2022-06-03T00:54:19Z

Convert vmx_apic_access_test to use vm_create_with_one_vcpu() and pass
around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.

Opportunistically make the "vm" variable local, it is unused outside of
main().
