Alex Orange a471a15c77 fb: Fix Bresenham algorithms for commonly used small segments. 
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=54168

Fix errors introducted in 863d528a9f. Said
patch does indeed remove the problematic writes to bad memory, however
it also introduces errors in the algoritm. This patch has the effect of
reverting said patch and adding an if in the proper location to catch
the out of bounds memory write without causing problems to the overall
algorithm.
