ada: Fix missing error on function call returning incomplete view
Testing for the presence of Non_Limited_View is not sufficient to detect
whether the nonlimited view has been analyzed because Build_Limited_Views
always sets the field on the limited view. Instead the discriminant is
whether this nonlimited view is itself an incomplete type.

* sem_ch4.adb (Analyze_Call): Adjust the test to detect the presence
of an incomplete view of a type on a function call.
