Log:
        PR c++/89831 - error with qualified-id in const member function.

Since the fix for 15272 we were remembering the wrong function to use at
instantiation time, because the type of the SCOPE_REF didn't reflect the
cv-quals of 'this'.  Conveniently, we can fix this by simplifying the code.

        * semantics.c (finish_non_static_data_member): Use object cv-quals
        in scoped case, too.
