====================
net/ncsi: More bug fixes

This series fixes 2 issues that were found during NCSI's availability
testing on BCM5718 and improves HNCDSC AEN handler:

   * PATCH[1] refactors the code so that minimal code change is put
     to PATCH[2].
   * PATCH[2] fixes the NCSI channel's stale link state before doing
     failover.
   * PATCH[3] chooses the hot channel, which was ever chosen as active
     channel, when the available channels are all in link-down state.
   * PATCH[4] improves Host Network Controller Driver Status Change
     (HNCDSC) AEN handler

Changelog
=========
v2:
   * Merged PATCH[v1 1/2] to PATCH[v2 1].
   * Avoid if/else statements in ncsi_suspend_channel() as Joel suggested.
   * Added comments to explain why we need retrieve last link states in
     ncsi_suspend_channel().
