wext: disconnect at init and deinit
To ensure the supplicant starts and ends with a clean slate (keys are already cleaned up at init and deinit time), force a null BSSID and bogus SSID to ensure the driver isn't connected to anything. Signed-off-by: Dan Williams <dcbw@redhat.com> (cherry picked from commit 2976121955ba0e2f52c09fbffc93f91dbf0d845b)
