Bucket.Stats() panics with index-out-of-range when iterating branch pages with zero elements. The leaf page path has a count != 0 guard, but the branch page path accesses branchPageElement(count - 1) without one. Wrap the branch element access in the same guard. Fixes etcd-io#1170 Signed-off-by: Quoc Bui <buiviquoc@gmail.com>
