A few of the free space tree exported functions have a 'btrfs_' prefix in their name, but most don't. Not only is this inconsistent, the preferred style is to have such a prefix, to avoid potential collisions in the future with other kernel code and offer a somewhat better readibility by making it obvious in calls sites that we are calling btrfs specific code. So add the 'btrfs_' prefix to all free space tree functions that are missing it.
