Konsta Holtta 4320877eb4 gpu: nvgpu: handle semaphore wraparound ...

Compare gpu semaphores in the kernel in the same way as the hardware
does: released if value is over threshold, but at most half of u32's
range. This makes it possible to skip zeroing the sema values when semas
are allocated, so that they'd be just monotonically increasing numbers
like syncpoints are.
