Bug detailed description:
-------------------------
It happens on GM45 with drm-intel-next-queued kernel, It works well on
drm-intel-fixes kernel. Many igt cases will fail after run ZZ_hangman. It
caused by igt commit.

    tests/lib: make sure the GPU is idle at test start and exit

    Bugzilla: <a class="bz_bug_link 
          bz_status_VERIFIED  bz_closed"
   title="VERIFIED FIXED - [SNB/IVB/HSW]I-G-T gem_wait_render_timeout Aborted"
   href="show_bug.cgi?id=64270">https://bugs.freedesktop.org/show_bug.cgi?id=64270</a>

    v2:
    - Make sure also that the GPU is idle at start and error exit of any
      test using drm_open_any(). (Daniel)
    v3:
    - actually call gem_quiescent_gpu() at exit
