cfg80211: clear SSID on disconnect/no connection
The SME state machine in cfg80211 uses the SSID stored in struct wireless_dev internally, but fails to clear it in multiple places (when giving up on a connection attempt and when disconnecting). This doesn't matter to the SME state machine, but does matter for IBSS. Thus, in those cases, clear the SSID to avoid messing up the IBSS state machine.
