  Skip frame when buffer overflow on UVC camera

Bug description:
  [Impact]
  Currently to use Intel RealSense, kernel needs to be patched [1].
  This SRU is to bring one of several fixes to Ubuntu kernel. 

  "Some cameras post inaccurate frame where next frame data overlap
  it. this results in screen flicker, and it need to be prevented."

  [Fix]
  "So this patch marks the buffer error to discard the frame where
  buffer overflow."

  [Test]
  I don't have such bad device so I can't test it. By reading through the
  code, this patch seems to be correct.

  [Regression Potential]
  Low. This patch has been in the kernel tree for more than two years and
  it doesn't bring any regression. So it should be fairly safe.
