[PATCHv4 05/14] x86/kvm: Do not try to disable kvmclock if it was not enabled

kvm_guest_cpu_offline() tries to disable kvmclock regardless if it is present in the VM. It leads to write to a MSR that doesn't exist on some configurations, namely in TDX guest: unchecked MSR access error: WRMSR to 0x12 (tried to write 0x) at rIP: 0x81106
