Gerd Hoffmann 3fcf15df00 ramfb: fix size calculation 
size calculation isn't correct with guest-supplied stride, the last
display line isn't accounted for correctly.

For the typical case of stride > linesize (add padding) we error on the
safe side (calculated size is larger than actual size).

With stride < linesize (scanlines overlap) the calculated size is
smaller than the actual size though so our guest memory mapping might
end up being too small.

While being at it also fix ramfb_create_display_surface to use hwaddr
for the parameters.  That way all calculation are done with hwaddr type
and we can't get funny effects from type castings.
