arc: flip if-condition predicates in secondary reload hook

The ARC code contains code which should only work with the old reload
pass. Such code is found in arc_secondary_reload hook, however it was
not properly quarded. Reverse the if-condition predicate such that
req_equiv_mem is called when lra is not in progress.
