gpu: nvgpu: skip classes in obj_alloc

Browse Source 
Currently, we are performing obj ctx alloction for bellow classes

 1. VOLTA_COMPUTE_A
 2. VOLTA_DMA_COPY_A
 3. VOLTA_CHANNEL_GPFIFO_A

In safety, we use Async CE but not GRCE.
So allocating obj context only for COMPUTE_A and return success(0) for
all other valid classes, after setting class in the channel struct.
