net/ncsi: Improve HNCDSC AEN handleropenbmc-4.4-20161021-1
This improves AEN handler for Host Network Controller Driver Status
Change (HNCDSC):
* The channel's lock should be hold when accessing its state.
* Do failover when host driver isn't ready.
* Configure channel when host driver becomes ready.
NOTE: The first one isn't applied to the code in dev-4.4.
