Tighten check for generated column in partition key expression

A generated column may end up being part of the partition key
expression, if it's specified as an expression e.g. "(<generated
column name>)" or if the partition key expression contains a whole-row
reference, even though we do not allow a generated column to be part
of partition key expression.  Fix this hole.
