3.8.13.3 -stable review patch. If anyone has any objections, please let me know.

From: Johannes Berg <johannes.berg@intel.com>
commit c815797663b72e3ac1736f1886538152bc48e4af upstream.
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.
