gpu: nvgpu: channel_setup_bind: must be bound to TSG

Browse Source 
In nvgpu_channel_setup_bind, return an error if the
channel isn't bound to a TSG, as future operations
rely on being bound.

Update usermode setup_bind test to bind channel to
the tsg before calling nvgpu_setup_bind

Manual port from rel-32
