Update the for_each_netdev_in_bond_rcu macro to iterate through network devices in the bond's network namespace instead of always using init_net. This change is safe because: 1. **Bond-Slave Namespace Relationship**: A bond device and its slaves must reside in the same network namespace. The bond device's namespace is established at creation time and cannot change. 2. **Slave Movement Implications**: Any attempt to move a slave device to a different namespace automatically removes it from the bond, as per kernel networking stack rules. This maintains the invariant that slaves must exist in the same namespace as their bond. This change is part of an effort to enable Link Aggregation (LAG) to work properly inside custom network namespaces. Previously, the macro would only find slave devices in the initial network namespace, preventing proper bonding functionality in custom namespaces.
