====================
bonding: fix bonding interface bugs

This patchset fixes lockdep problem in bonding interface

1. The first patch is to add missing netdev_update_lockdep_key().
After bond_release(), netdev_update_lockdep_key() should be called.
But both ioctl path and attribute path don't call
netdev_update_lockdep_key().
This patch adds missing netdev_update_lockdep_key().

2. The second patch is to export netdev_next_lower_dev_rcu symbol.
netdev_next_lower_dev_rcu() is useful to implement the function,
which is to walk their all lower interfaces.
This patch is actually a preparing patch for the third patch.

3. The last patch is to fix lockdep waring in bond_get_stats().
The stats_lock uses a dynamic lockdep key.
So, after "nomaster" operation, updating the dynamic lockdep key
routine is needed. but it doesn't
So, lockdep warning occurs.

Change log:
v1 -> v2:
 - Update headline from "fix bonding interface bugs"
   to "bonding: fix bonding interface bugs"
 - Drop a patch("bonding: do not collect slave's stats")
 - Add new patches
   - ("net: export netdev_next_lower_dev_rcu()")
   - ("bonding: fix lockdep warning in bond_get_stats()")
