net, team, bonding: Add netdev_base_features helper
[ Upstream commit d2516c3a53705f783bb6868df0f4a2b977898a71 ]
Both bonding and team driver have logic to derive the base feature
flags before iterating over their slave devices to refine the set
via netdev_increment_features().
Add a small helper netdev_base_features() so this can be reused
instead of having it open-coded multiple times.
