dev-amdgpu: Remove default callback in mem manager API
In almost all cases reading/writing using the GPU memory manager will
want to wait until that read or write is complete. Therefore, change the
API to not default to no callback so that the user must explicitly
specify nullptr indicating they do not want to wait for completion.
Updates a write call which cannot use a callback due to being atomic in
the base gpu device code.
