x86: KVM guest: kvm_get_tsc_khz: return khz, not lpj
kvm_get_tsc_khz() currently returns the previously-calculated preset_lpj value, but it is in loops-per-jiffy, not kHz. The current code works correctly only when HZ=1000. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
