Jeff Mahoney 95617d6932 btrfs: cleanup, stop casting for extent_map->lookup everywhere ...

Overloading extent_map->bdev to struct map_lookup * might have started out
as a means to an end, but it's a pattern that's used all over the place
now. Let's get rid of the casting and just add a union instead.
