xf86drm: Fix error path in drmGetDevice2
In drmGetDevice2 when no local device is found or when
drm_device_has_rdev filters out all devices, *device might be left
uninitialized causing drmGetDevice2 to not return error - since
it's only returned when *device == NULL.
Above leads to crash in the firefox in system with amdgpu.
With this change firefox displays:
libGL error: MESA-LOADER: failed to retrieve device information
libGL error: unable to load driver: amdgpu_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: amdgpu
libGL error: MESA-LOADER: failed to retrieve device information
libGL error: unable to load driver: amdgpu_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: amdgpu
and doesn't crash.
