testing/drivertest: Fix timing issues on QEMU and sims.

Browse source 
Since sim and qemu are not cycle accurate simulators, if the vCPU thread is preempted by other high priority tasks, it may cause timing issues. This is easy to happen when the test machine is busy. This commit modifies the condition of timing error and prints out the latency as a warning.
