Currently, o2net_accept_one() is allowed to accept a connection from listening node itself, such a fake connection will not be successfully established due to no handshake detected afterwards, and later end up with triggering connecting worker in a loop. We're going to fix this by treating such connection request as 'invalid', since we've got no chance of requesting connection from a node to itself in a OCFS2 cluster. The fix doesn't hurt user's scan for o2net-listener, it always gets a successful connection from userpace.
