vim-patch:8.0.0520: using a function pointer while the function is known (#8513)

Browse Source 
Problem:    Using a function pointer instead of the actual function, which we
            know.
Solution:   Change mb_ functions to utf_ functions when already checked for
            Unicode. (Dominique Pelle, closes vim/vim#1582)
