If a device has smooth scrolling axes, but submits scroll button events, we convert those to motion events and update the valuators. For legacy button events, the valuator mask is likely unset though, causing add_to_scroll_valuator() to return early, leaving us with an empty mask. That again skipped the rest of the code and no events were generated.
Fix it by making sure that the scroll valuator in the mask is at least initialized to 0. Broke evdev wheel emulation, introduced by 54476b5e4461ff523e935961affabcf0de12c556.
