This assumes we'll be able to allocate chunks during transaction commit, but since nothing does a LIMIT flush during the transaction commit this won't actually happen unless we happen to run shy of actual space. We already take into account a full fs in btrfs_check_space_for_delayed_refs() so just kill this extra check to make sure we're ending the transaction when we need to.
