Subject: [PATCH net-next 0/2] bonding: fix enslaving a dev without mtu setting support

Hi,

With the introduction of bond_free_slave() we need to have slave->bond
populated before calling it, however if the dev_mtu_set(slave, mtu) fails,
we call bond_free_slave() before actually setting slave->bond, and thus
we'll panic.

Fix this by populating slave->bond (and ->dev, it seems appropriate) as
early as possible.

Also, remove a harmful check for NULL in bond_get_bond_by_slave(), as it's
only hiding the real problem and making it harder to debug.
