2452d12 by Guy Harris (guy@xxxxxxxxxxxx):

    Clean up some issues with get_iface_list_string().
    
    Remove an assignment of NULL to a variable when it's in a branch of code
    where the variable's already known to be NULL.  Found by PVS-Studio.
    
    Pull get_display_name_for_interface() into the one place it's used.
    That:
    
        allows us to eliminate a test as, inside the loop where it's called,
        the loop index is what's passed to it, and the loop tests whether
        it's in range, so the test will never fail;
    
        means we just set interface_opts once, for both of the places it's
        used.
    
    Then we fix that code so that it sets interface_opts->descr to a
    generated descriptive name if it *is* null, rather than if it's *not*
    null.
    
    That should clean up some issues found by 1) PVS-Studio and 2) me.
