If an error occurs in amdgpu_device_init() after adev->rmmio has been set, its caller amdgpu_driver_load_kms() will skip runtime pm initialization and call amdgpu_driver_unload_kms(), which acquires a runtime pm ref that is leaked. Balance by releasing a runtime pm ref in the error path of amdgpu_driver_load_kms().
