Fix dead stores found by scan-build

In addition to removing unused code, two minor problems are fixed:
 (1) `resize set` and `resize adjust` did not error when given
too many arguments.
 (2) `orientation` was incorrectly overridden to be 'U' for
scroll events in the swaybar tray `handle_click` function.
