Subject: fbcon: fix rotate upside down crash
From: Stefani Seibold <stefani@xxxxxxxxxxx>
Fix the rotate_ud() function not to crash in case of a font which has not
a width of multiple by 8: The inner loop of the font pixel copy should not
access a bit outside the font memory area. Subtract the shift offset from
the font width will prevent this.
