Btrfs: fix how we set max_size for free space clusters
This patch fixes a problem where max_size can be set to 0 even though we filled the cluster properly. We set max_size to 0 if we restart the cluster window, but if the new start entry is big enough to be our new cluster then we could return with a max_size set to 0, which will mean the next time we try to allocate from this cluster it will fail. So set max_extent to the entry's size. Tested this on my box and now we actually allocate from the cluster after we fill it.
