gpu: nvgpu: make .tsg_unbind_channel one layer lower

Browse Source 
The message to tell RM server to unbind channel has to be sent after
client unbinds the channel and before client calls tsg release. The
channel has to belong to a tsg on RM server before client submit a
runlist to remove the channel. Or there's a bare channel problem.

By moving .tsg_unbind_channl one layer lower, gk20a_tsg_unbind_channel()
will be common functions for all chip, and it'll call tsg release after
call .tsg_unbind_channel. So vgpu won't need to worry about tsg was
released before sending msg to RM server.
