When there are no framebuffer attachments, fb->width and fb->height will
be 0. Subtracting 1 results in 4294967295 which is too large for the
field, causing genxml assertions when trying to create the packet.
In this case, we can just program it to 1.

I'm expecting a NAK from Jason on this patch. Hopefully we can find a
real solution to this problem...
