cfg80211: hold BSS over association process
This fixes the potential issue that the BSS struct that we use and later assign to wdev->current_bss is removed from the scan list while associating. Also warn when we don't have a BSS struct in connect_result unless it's from a driver that only has the connect() API. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
