When the suballocator was unable to provide a suitable buffer for the MMUv1 linear window, we roll back the GPU initialization. As the GPU is runtime resumed at that point we need to clear the kernel cmdbuf suballoc entry to properly skip any attempt to manipulate the cmdbuf when the GPU gets shut down in the runtime suspend later on.
