pan/lib: divide extent by tile-extend, not itself

Browse source 
Dividing this by itself is nonsensical, and just always gives us one.
That's obviously not what we want here.

But in this case we also know that the extent is divisible by the tile
extent, so there's no need for DIV_ROUND_UP, we can just divide.
