bonding: add slave_changelink support and use it for queue_id
This patch adds support for slave_changelink to the bonding and uses it
to give the ability to change the queue_id of the enslaved devices via
netlink. It sets slave_maxtype and uses bond_changelink as a prototype for
bond_slave_changelink.
Example/test command after the iproute2 patch:
ip link set eth0 type bond_slave queue_id 10
