[PATCH] fbcon: replace mono_col macro with static inline

[Harvey Harrison]

Use __u32 for max_len to match the declaration of length in the
struct fb_bitfield.

Suppresses sparse shadowed variable warnings from the nested max()
macros:
drivers/video/console/fbcon.h:130:8: warning: symbol '_x' shadows an earlier one
drivers/video/console/fbcon.h:130:8: originally declared here
drivers/video/console/fbcon.h:130:8: warning: symbol '_x' shadows an earlier one
drivers/video/console/fbcon.h:130:8: originally declared here
drivers/video/console/fbcon.h:130:8: warning: symbol '_y' shadows an earlier one
drivers/video/console/fbcon.h:130:8: originally declared here
