WiFi: "Connect" option disappear after rotating.

The connect option disappears because there is a problem in saving and
restoring the state of the access point showed in the dialog box. When a
rotation accurs, the framework calls onSaveInstanceState(Bundle outState)
of the wifisettings activity. In this method, the state of the access is
saved, but not its rssi level. After a rotation, when restoring the access
point state, the rssi is initialized to the default value, which means out of
range. This is why the connect option is not displayed. I fixed the issue by
saving and restoring the rssi level of the access point.
