Fix handling of non-key columns get_index_column_opclass()
f2e40380 introduces support of non-key attributes in GiST indexes. Then if
get_index_column_opclass() is asked by gistproperty() to get an opclass of
non-key column, it returns garbage past oidvector value. This commit fixes
that by making get_index_column_opclass() return InvalidOid in this case.
