The check to detect if a rule is in resize was done incorrectly,
this can lead to an incorrect function call upon completion for
rules which are not in resize (move).
Since the resize_info is in a union we cannot rely only on the
pointer value but also need to make sure the matcher is in resize
process, this assures us the resize info is valid.
