Subject: drm/amdgpu: Fix NULL ptr on driver unload due to init failure.
Git-commit: b6356df3eb9ad9ae12efb4ec37d5615065e51d8b
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Problem:
When unloading due to failure amdgpu_device_fini was called twice
which was leading to NULL ptr in amdgpu_irq_disable_all.
Fix:
Call amdgpu_device_fini only once from amdgpu_driver_unload_kms.
