Darren Kenny 7ce3259f67 video/fb/fbfill: Fix potential integer overflow ...

The multiplication of 2 unsigned 32-bit integers may overflow before
promotion to unsigned 64-bit. We should ensure that the multiplication
is done with overflow detection. Additionally, use grub_sub() for
subtraction.

Fixes: CID 73640, CID 73697, CID 73702, CID 73823
