fbcon: Call fbcon_mode_deleted/new_modelist directly
I'm not entirely clear on what new_modelist actually does, it seems exclusively for a sysfs interface. Which in the end does amount to a normal fb_set_par to check the mode, but then takes a different path in both fbmem.c and fbcon.c. I have no idea why these 2 paths are different, but then I also don't really want to find out. So just do the simple conversion to a direct function call. v2: static inline for the dummy versions, I forgot.
