Wifi: Issue Disconnect when Ip is changed

When the IP address assignment on the WLAN interface changes
from STATIC to STATIC the requisite routes are not getting added
by the connectivity service. Hack this by simulating a disconnect
and a reconnect , which is when the routes shall get added
properly.
