iris: finish aux import on get_param

A buffer and its aux are imported separately, if the aux import is
not completed yet when resource_get_param is called, merge the
separate aux a.k.a the 2nd image into the main image.

Fixes: 246eebba4a8 ("iris: Export and import surfaces with modifiers that have aux data")
