Bug detailed description:

Subcase reimport-vs-gem_close-race  of prime_self_import failed.

It's intel-gpu-tools regression issue:

2f2c491cf3167befe7c79e4b17afb4f6284dfc84 is the first bad commit

    lib/drmtest: don't dup quiescent fd

    If we dup the fd, we are in mercy of the context banning
    of the test application. Better to have our own to guarantee
    that gem_quiescent_gpu won't find itself banned on exit.
