Jan H. Schönherr b9a58de545 vgacon: Prevent faulty bootparams.screeninfo from causing harm
If a zero for the number of colums or rows manages to slip through,
gotoxy() will underflow vc->vc_pos, causing the next action on the
referenced memory to end with a page fault.

Make the check in vgacon_startup() more pessimistic to prevent that.
