We were returning PTR_ERR() on a NULL pointer, which obviously won't work. nvkm_engine_ref() will return an error in case something went wrong.

The nvkm_engine_ref() function returns error pointers, not NULL on error. I fixed that but I also had to reverse some of the checks so it didn't become too convoluted.

This series is intended to add support for shutting down the GPU on kernel shutdown/reboot using the ->shutdown() hook, similar to what amdgpu does. This is mainly intended to workaround a bios issue on the P50 that was preventing nouveau from initializing the dedicated GM107 GPU on that system properly. You can find more details on this issue in the patch labeled "Shut down GPU on kernel
