aoe: ignore vendor extension AoE responses
The Welland ME-747K-SI AoE target generates unsolicited AoE responses that are marked as vendor extensions. Instead of ignoring these packets, the aoe driver was generating kernel messages for each unrecognized response received. This patch corrects the behavior.
