cfg80211: check wdev->netdev in connection work
If a P2P-Device is present and another virtual interface triggers the connection work, the system crash because it tries to check if the P2P-Device's netdev (which doesn't exist) is up. Skip any wdevs that have no netdev to fix this. Cc: stable@vger.kernel.org Reported-by: YanBo <dreamfly281@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
