[dev] [dwm] bugfix for multi monitor setup

Hello and thanks for the wonder that is dwm.

Below is a patch for issues I have found with 2 monitors where one
monitor is below another.

The issue can be found when moving a floating window that fills the
entire available area from one monitor to another. (This is with a
borderpx of 0)

thanks,
Brian
