fbdev: kill sparse warning in deferred IO
Kill the following in fb_defio.c:
drivers/video/fb_defio.c:40:43: warning: incorrect type in argument 1 (different address spaces)
drivers/video/fb_defio.c:40:43: expected void *addr
drivers/video/fb_defio.c:40:43: got char [noderef] *screen_base<asn:2>
The framebuffer memory of these types of devices are allocated from system
RAM.
