QEMU's kvmclock device is only created when KVM PV feature bits for kvmclock (KVM_FEATURE_CLOCKSOURCE/KVM_FEATURE_CLOCKSOURCE2) are exposed to the guest. With 'kvm=off' cpu flag the device is not created and we don't call KVM_GET_CLOCK/KVM_SET_CLOCK upon migration. It was reported that without these call at least Hyper-V TSC page clocksouce (which can be enabled independently) gets broken after migration. Switch to creating kvmclock QEMU device unconditionally, it seems to always make sense to call KVM_GET_CLOCK/KVM_SET_CLOCK on migration. Use KVM_CAP_ADJUST_CLOCK check instead of CPUID feature bits.
