kernel - Fix lockmgr lock mismatch panics when iwn used without wlan

* If if_iwn is ifconfig'd without going through wlan the wlan_serializer
  is not held during the firmware load stage, resulting in a panic.
  Acquire the serializer for this case.

* Note: iwn worked fine with wlan, but this fixes an annoying panic when
  people try to mess with it without wlan.
