Currently uninit is sometimes done twice in error flows, and is sprinkled a bit all over the place. Improve the clarity of the design by moving all uninit only into ndo_uinit. Some duplication is removed: - Sometimes IPOIB_STOP_NEIGH_GC was done before unregister, but this duplicates the process in ipoib_neigh_hash_init - Flushing priv->wq was sometimes done before unregister, but that duplicates what has been done in ndo_uninit Uniniting the IB event queue must remain before unregister_netdev as it requires the RTNL lock to be dropped, this is moved to a helper to make that flow really clear and remove some duplication in error flows. If register_netdev fails (and ndo_init is NULL) then it almost always calls ndo_uninit, which lets us remove all the extra code from the error unwinds. The next patch in the series will close the 'almost always' hole by pairing a proper ndo_init with ndo_uninit.
