KVM: kvmtrace: replace get_cycles with ktime_get v3
The current kvmtrace code uses get_cycles() while the interpretation would be easier using using nanoseconds. ktime_get() should give at least the same accuracy as get_cycles on all architectures (even better on 32bit archs) but at a better unit (e.g. comparable between hosts with different frequencies.
