kvm: Allow invtsc migration if tsc-khz is set explicitly
We can safely allow a VM to be migrated with invtsc enabled if
tsc-khz is set explicitly, because:
* QEMU already refuses to start if it can't set the TSC frequency
to the configured value.
* Management software is already required to keep device
configuration (including CPU configuration) the same on
migration source and destination.
