gpu: nvgpu: make preemption modes unsigned

graphics and compute preemption modes are currently
defined as int
But it is more logical to have them as unsigned int

Also, we treat preemption modes as unsigned almost
everywhere in the code

Fix prints in gk20a_fifo_sched_debugfs_seq_show() to
print U32_MAX with %d which is same as printing -1
