Use vcpu_idx to identify vCPU0 when updating HyperV's TSC page, which is shared by all vCPUs and "owned" by vCPU0 (because vCPU0 is the only vCPU that's guaranteed to exist). Using kvm_get_vcpu() to find vCPU works, but it's a rather odd and suboptimal method to check the index of a given vCPU. No functional change intended.
