bonding: fix rtnl locking merge error
Looks like I incorrectly merged one of the rtnl lock changes,
so that one function, bonding_show_active_slave, held rtnl but didn't
release it, and another, bonding_store_active_slave, never held rtnl but
did release it.
Fixed so the first function doesn't mess with rtnl, and the
second correctly acquires and releases rtnl.
