gpu: nvgpu: remove g->ops.gr.halt_pipe hal

Browse Source 
Hal API g->ops.gr.halt_pipe() is defined in unsafe unit hal.gr.gr
It is called from safe unit, and it calls into API
g->ops.gr.falcon.ctrl_ctxsw() which is also safe

Hence get rid of unsafe API g->ops.gr.halt_pipe().
Caller now directly calls hal.gr.falcon API to halt pipe
