Patch-mainline: v4.20-rc1
Subject: KVM: x86: hyperv: consistently use 'hv_vcpu' for 'struct kvm_vcpu_hv' variables
Git-commit: 1779a39f786397760ae7a7cc03cf37697d8ae58d
References: fate#323887

Rename 'hv' to 'hv_vcpu' in kvm_hv_set_msr/kvm_hv_get_msr(); 'hv' is
'reserved' for 'struct kvm_hv' variables across the file.
