Change scrollbars_highlight_off() and scrollbars_highlight_on() to void

Since the return value of scrollbars_highlight_on() and scrollbars_highlight_off()
is not used and even no value is returned, change the function signature to 
a return type of void.

This fixes following compile warning:

  scrollbars.c: In function 'scrollbars_highlight_off':
  scrollbars.c:337: warning: control reaches end of non-void function
  scrollbars.c: In function 'scrollbars_highlight_on':
  scrollbars.c:329: warning: control reaches end of non-void function
