matroxfb: avoid -Warray-bounds warning

The open-coded list_for_each_entry() causes a harmless warning:

drivers/video/fbdev/matrox/matroxfb_base.c: In function 'matroxfb_register_driver':
include/linux/kernel.h:856:3: warning: array subscript -98 is outside array bounds of 'struct list_head[1]' [-Warray-bounds]

Use the normal list_for_each_entry instead.
