KVM: arm64: Fix kvm_vcpu_initialized() macro parameter 



The macro is defined with parameter 'v' but the body references the
literal token 'vcpu' instead, causing it to silently operate on whatever
'vcpu' resolves to in the caller's scope rather than the value passed by
the caller. All current call sites happen to use a variable named 'vcpu',
so the bug is latent.
