bonding: fix enslavement slave link notifications
Currently, link notifications are not sent by bond_set_slave_link_state() upon enslavement if the slave is enslaved when up. This happens because slave->link default init value is 0, which is the same as BOND_LINK_UP, resulting in bond_set_slave_link_state() ignoring this transition. This patch sets the default value of slave->link to BOND_LINK_NOCHANGE, assuring it will count as a state transition and thus trigger notification logic.
