Subject[PATCH v2 076/144] KVM: selftests: Convert hyperv_svm_test away from VCPU_ID
From
Convert hyperv_svm_test to use vm_create_with_one_vcpu() and pass around a
'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this is
a "functional" change in the sense that the test now creates a vCPU with
vcpu_id==0 instead of vcpu_id==1. The non-zero VCPU_ID was 100% arbitrary
and added little to no validation coverage. If testing non-zero vCPU IDs
is desirable for generic tests, that can be done in the future by tweaking
the VM creation helpers.

Opportunistically use vcpu_run() instead of _vcpu_run(), the test expects
KVM_RUN to succeed.
