drm/gpuvm: Fix comment to reflect remap operation operand status

Browse Source 
When a new mapping intersects with an existing GPU VA, but either
end lies before or beyond the existing VA's edges, then the prev
and next mapping operations part of a remap will reflect this
condition by being set to NULL.
