gpu: nvgpu: add refcounting for TSG
Add refcounting for TSGs and manage the refcounts as below :
- initialize ref when TSG is opened
- get ref when channel is bound to TSG
- drop the ref when channel is unbound (i.e. during channel close)
- drop the ref when TSG is closed
- when refcount drops to zero, we free the TSG
This refcounting makes it possible to close channels or TSG
in any order
