gpu: nvgpu: move check_gp_put() and update_gp_get() to worker
We currently call check_gp_put() and update_gp_get()
in submit path and this takes about 5uS for both checks
check_gp_put() - 3.5 uS
update_gp_get() - 1.5 uS
But this book-keeping can be moved to gk20a_channel_update()
to save some submit time
Note that check_gp_put() needs to be done inside submit
lock
