bonding: re-evaluate force_primary when the primary slave name changes
[ Upstream commit eb55bbf865d9979098c6a7a17cbdb41237ece951 ] There is a timing issue under active-standy mode, when bond_enslave() is called, bond->params.primary might not be initialized yet. Any time the primary slave string changes, bond->force_primary should be set to true to make sure the primary becomes the active slave.
