qemu: The TSC tolerance interval should be closed

Browse Source 
The kernel refuses to set guest TSC frequency less than a minimum
frequency or greater than maximum frequency (both computed based on the
host TSC frequency). When writing the libvirt code with a reversed logic
(return success when the requested frequency falls within the tolerance
interval) I forgot to include the boundaries.
