Remove orphan state wipe from UnloadBlockIndex.

TheBlueMatt · TheBlueMatt · commit 87c35f584397 · 2016-12-01T16:08:34.000-08:00
As orphan state is now "network state", like in d6ea737, UnloadBlockIndex is only used during init if we end up reindexing to clear our block state so that we can start over. However, at that time no connections have been brought up as CConnman hasn't been started yet, so all of the network processing state logic is empty when its called.
