[PATCH xf86-video-amdgpu 2/2] amdgpu_probe: Do not close server managed drm fds

From: Hans De Goede <hdegoede at redhat.com>

This fixes the xserver only seeing AMD/ATI devices supported by the amdgpu
driver, as by the time xf86-video-ati gets a chance to probe them, the
fd has been closed.

This fixes e.g. Xorg not seeing the dGPU on a Lenovo Thinkpad E465 laptop
with a CARRIZO iGPU and a HAINAN dGPU.

v2: Rebased on top of new patch 1.
