bonding: fix race condition in bonding_store_slaves_active
Race between bonding_store_slaves_active() and slave manipulation
functions. The bond_for_each_slave use in bonding_store_slaves_active()
is not protected by any synchronization mechanism.
NULL pointer dereference is easy to reach.
Fixed by acquiring the bond->lock for the slave walk.
v2: Make description text < 75 columns
