igb: improve handling of disconnected adapters
commit 7b06a6909555ffb0140733cc4420222604140b27 upstream.
Clean up array_rd32 so that it uses igb_rd32 the same as rd32, per the
suggestion of Alexander Duyck, and use io_addr in more places, so that
we don't have the need to call E1000_REMOVED (which simply looks for a
null hw_addr) nearly as much.
