drm/amdgpu: Check if NBIO funcs are NULL in amdgpu_device_baco_exit

Browse source

[ Upstream commit 0cdb3f9740 ]

The special case for VM passthrough doesn't check adev->nbio.funcs
before dereferencing it. If GPUs that don't have an NBIO block are
passed through, this leads to a NULL pointer dereference on startup.
