    drm/i915: Reduce differences with Linux in i915_gem_fault()
    
    * The convoluted DragonFly-specific lock/unlock/try again VM fault
      handling code path was not treating gem objects in the same way
      during each try.
    
    * vma->pin_count could be zero, leading to a kernel panic.
