drm/xe: Ensure that we don't access the placements array out-of-bounds
Ensure, using xe_assert that the various try_add_<placement> functions
don't access the bo placements array out-of-bounds.
v2:
- Remove the places argument to make sure the xe_assert operates on
the array we're actually populating. (Matthew Auld)
