    i915/gem_cpu_reloc: Do the can-store-dword check at start

    igt doesn't handle skipping from inside igt_fork very gracefully and
    crashes instead of reporting the lack of requirements. One solution
    would be to fix igt, but far easier is to just move the requirement
    checking around to do it before we even fork.
