Btrfs: memset to avoid stale content in btree leaf
commit 851cd173f06045816528176001cf82948282029c upstream.
This is an additional patch to
"Btrfs: memset to avoid stale content in btree node block".
This uses memset to initialize the unused space in a leaf to avoid
potential stale content, which may be incurred by pushing items
between sibling leaves.
