Avoid compiler warning in non-assert builds

After 01575ad, expand_single_inheritance_child()'s parentOID variable is read only in an Assert, provoking a compiler warning in non-assert builds. Fix that by marking the variable with PG_USED_FOR_ASSERTS_ONLY. Per report and suggestion from David Rowley Discussion: https://postgr.es/m/CAApHDvpjA_8Wxu4DCTRVAvPxC9atwMe6N%2ByvrcGsgb7mrfdpJA%40mail.gmail.com
