[PATCH net-next v3 5/5] bonding: handle NETIF_F_HW_NETFUNC_OFFLOAD flag to bonding feature mask

From: Roopa Prabhu <redacted>

We want bond to pick up the offload flag if any of its slaves have it.

NETIF_F_HW_NETFUNC_OFFLOAD flag is added to the mask, so that
netdev_increment_features does not ignore it.

If this needs to be under CONFIG_NET_SWITCHDEV, I can do so.
