Btrfs: don't skip writing out a empty block groups cache
I noticed a slight bug where we will not bother writing out the block group cache's space cache if it's space tree is empty. Since it could have a cluster or pinned extents that need to be written out this is just not a valid test. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
