KVM: x86: rewrite handling of scaled TSC for kvmclock
This is the same as before:
kvm_scale_tsc(tgt_tsc_khz)
= tgt_tsc_khz * ratio
= tgt_tsc_khz * user_tsc_khz / tsc_khz (see set_tsc_khz)
= user_tsc_khz (see kvm_guest_time_update)
= vcpu->arch.virtual_tsc_khz (see kvm_set_tsc_khz)
However, computing it through kvm_scale_tsc will make it possible
to include the NTP correction in tgt_tsc_khz.
