Helge Deller e431a54055 fbcon: Disallow setting font bigger than screen size 
upstream commit id: 65a01e601d

Prevent that users set a font size which is bigger than the physical screen.
It's unlikely this may happen (because screens are usually much larger than the
fonts and each font char is limited to 32x32 pixels), but it may happen on
smaller screens/LCD displays.
