gpu: nvgpu: fix TSG leak from CDE code
In gk20a_cde_remove_ctx(), we unbind the channel from TSG and
close the channel. But we do not drop the TSG refcount leaking
the TSG reference
After allocating sufficient contexts, we see TSG creation fails as below
nvgpu: 17000000.gp10b: gk20a_cde_load:1286 [ERR] cde: could not create TSG
Fix this by explicitly dropping TSG refcount
Also, do not explicitly unbind the channel from TSG
gk20a_channel_close() will internally unbind the channel from TSG
