fbdev: ignore VESA modes if framebuffer is disabled
If the option vga=<VESA graphics mode> is added to the boot parameter, it will activate graphics mode, but without any framebuffer support, the user is left with an unusable display. Change the behavior such that the user is instead prompted for another mode (ala vga=ask). NOTE: People can always use vbetool to set a graphics mode if this is really desired, but the number of people doing this approaches zero.
