drm/xe/query: Fix topology query pointer advance
The topology query helper advanced the user pointer by the size
of the pointer, not the size of the structure. This can misalign
the output blob and corrupt the following mask. Fix the increment
to use sizeof(*topo).
There is no issue currently, as sizeof(*topo) happens to be equal
to sizeof(topo) on 64-bit systems (both evaluate to 8 bytes).
Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs")
