hostapd: Fix WPA, IEEE 802.1X, and WPS deinit in cases where init fails

Browse source 
With driver wrappers that implement set_privacy(), set_generic_elem(),
set_ieee8021x(), or set_ap_wps_ie(), it was possible to hit a NULL
pointer dereference in error cases where interface setup failed and
the network configuration used WPA/WPA2, IEEE 802.1X, or WPS.

Fix this by skipping the driver operations in case the driver interface
is not initialized.
