widl: Avoid duplicate assignments in resolve_expression.

[Gerald Pfeifer]

At the beginning of this function we have result.is_variable = FALSE,
so these assignments are redundant.  (An alternative patch would be
to remove the initial assignment and have every case fully initialize
the result structure.)
