Chris Mason d57e62b897 Btrfs: try to free metadata pages when we free btree blocks 
COW means we cycle though blocks fairly quickly, and once we
free an extent on disk, it doesn't make much sense to keep the pages around.

This commit tries to immediately free the page when we free the extent,
which lowers our memory footprint significantly.
