bonding: fix initial link status of slave

On Fortville NIC, link status change interrupt callback is not executed when
slave in bonding is (re-)started. It causes that slave's NIC is inactive even
if its link status is up on the start.

This patch invokes lsc callback, just after port's start, to check its initial
link status and manage properly.
