gpu: nvgpu: get VM reference for TSG
We store a reference to common address space of channels
in struct tsg_gk20a without increasing the refcount
This could result in freeing the address space even when
some channel in TSG needs it or when we need to free
common gr_ctx
Fix this by getting ref using gk20a_vm_get() when we store
the VM reference. We drop this reference with
gk20a_vm_put() when closing the TSG
