If the driver is detected to use cfg80211, we can rely on it being able to disconnect with SIOCSIWMLME commands and to use empty SSID as a way to stop it from associating when we are in progress of configuring the driver for association. Consequently, we can remove the hack that uses random 32-octet SSID to force disconnection and re-order association commands to match the expectations that cfg80211 has for WEXT ioctls. This gets rid of extra scan rounds and attempts to associate with the silly 32-octet SSID.
