[PATCH] fbcon: Console Rotation - Fix wrong shift calculation

The shift value (amount to shift the bitmap so first pixel starts at
origin(0,0)) is incorrect.  This causes corrupted characters or a kernel crash
if fontwidth is not divisible by 8 at 270 degrees, or fontheight not divisible
by 8 at 180 degrees.

Report and part of the fix contributed by Knut Petersen.
