libpayload: corebootfb: Add null check for framebuffer address

If the framebuffer address is zero the corebootfb_init() function
should abort and not attempt to use it for video, otherwise it
will likely hang.

This was tested by booting on a board that does not have a display
attached and includes the previous patch to zero the framebuffer
structure in the coreboot tables.
