  [analyzer] Fix crash when casting the result of a malformed fptr call (#111390)

Ideally, we wouldn't workaround our current cast-modeling, but the
experimental "support-symbolic-integer-casts" is not finished so we need
to live with our current modeling.

Ideally, we could probably bind `UndefinedVal` as the result of the call
even without evaluating the call, as the result types mismatch between
the static type of the `CallExpr` and the actually function that happens
to be called.

Nevertheless, let's not crash.
