cfg80211: check wdev->netdev in connection work
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.
