intel: Track known prime buffers for re-use If the application sends us a file descriptor pointing at a prime buffer that we've already got, we have to re-use the same bo_gem structure or chaos will result. Track the set of all known prime objects and look to see if the kernel has returned one of those for a new file descriptor. Also checks for prime buffers in the flink case.
