Subject: [PATCH net-next V2 4/8] net/bonding: Take update_features call out of XFRM funciton

In preparation for more cases that call netdev_update_features().

While here, move the features logic to the stage where struct bond
is already updated, and pass it as the only parameter to function
bond_set_xfrm_features().
