f83447d134 gpu: nvgpu: mm: make num_user_mapped_buffers a u32 
The vm object num_user_mapped_buffers was declared as an int. However,
it is an unsigned value. Being a signed value required a cast to
unsigned when calling nvgpu_big_zalloc() which causes a CERT-C INT31
violation. So, avoid the cast and use an unsigned type. And fix related
INT30 violations related to num_user_mapped_buffers as well.

To avoid introducing new MISRA/CERT-C violations, update the upstream
user of these changes, fifo/channel.c and make the equivalent uses of
this value, num_mapped_buffers a u32 as well.

d16ddb244f gpu: nvgpu: remove g->ops.gr.halt_pipe hal 
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
