intel: use throttle ioctl for throttling
Rather than waiting on the first batch after the last swapbuffers to be retired, call into the kernel to wait upon the retirement of any request less than 20ms old. This has the twofold advantage of (a) not blocking any other clients from utilizing the device whilst we wait and (b) we attain higher throughput without overloading the system.
