[dwm] togglebar/xrandr with dwm 4.1

Hi,

changing resolutions while the bar is visible works as desired.

But when the bar is invisible and the resolution is changes, the bar
height is still subtracted from the screen size in configurenotify().
Windows won't go fullscreen anymore. After calling togglebar twice
everything is ok.

I don't have a patch as of yet, perhaps it's enough to just call
updatebarpos() after the screen size got updated in configurenotify().

Regards,
Christian
