gpu: nvgpu: tear down TSG on unbind HAL failure

Browse Source 
Currently nvgpu_tsg_unbind ignores return code from
g->ops.tsg.unbind_channel. For consistency, tear down
TSG in case an error occurs in the unbind HAL.

Also make sure to restore valid ops for fifo.preempt_tsg
in test_gr_setup_free_obj_ctx, to avoid unbind failure.
