x86/kvm/hyper-v: don't announce GUEST IDLE MSR support

Browse Source 
HV_X64_MSR_GUEST_IDLE_AVAILABLE appeared in kvm_vcpu_ioctl_get_hv_cpuid()
by mistake: it announces support for HV_X64_MSR_GUEST_IDLE (0x400000F0)
which we don't support in KVM (yet).

Fixes: 2bc39970e9 ("x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID")
