gpu: nvgpu: Deterministic submit fix
Fix some simple pointer arithmetic errors in the deterministic submit
path. The lockless allocator was doing a subtraction to determine the
correct offset of the element to free. However, this subtraction was
using the base address and a numeric offset - not a pointer offset. Thus
the difference computed was in bytes not in elements of the block size.
The fix is simple: just divide by the block size.
Also this modifies the debugging statement a bit so that a bit more
information is printed at more useful times.
Lastly, a pointer to numeric cast was fixed in the fence code.
