network: reconfigure link after coming back from sleep

Previously, link was reconfigured with `link_carrier_reset()`, but it
just re-request to configure static addresses, routes, etc, and restart
engines (e.g. DHCP client).
However, after coming back from sleep, several link information may be
changed, especially the wifi access point may be different. So, we may
need to reconfigure the interface.
