[Intel-gfx] [PATCH 1/2] intel_device: Don't close the fd on probe failure if it is server managed

[Hans de Goede]

I hit this corner case when testing a single X server spanning both intel
gfx + an usb display link adapter driven by xf86-video-modesetting.

In this scenario the intel driver gets its platformProbe method called first,
and if it then closes the server managed fd, the xf86-video-modesetting gets
EBADFD errors.
