Assert that partition inherits from only one parent in MergeAttributes()

A partition inherits only from one partitioned table and thus inherits
a column definition only once.  Assert the same in MergeAttributes()
and simplify a condition accordingly.

Similar definition exists about line 3068 in the same function.
