Subject: [PATCH net-2.6] ixgbe: fix panic when shutting down system with
	WoL enabled


This patch added to 2.6.34:

	commit 5f6c01819979afbfec7e0b15fe52371b8eed87e8
	Author: Jesse Brandeburg <jesse.brandeburg@...el.com>

	    ixgbe: fix bug with vlan strip in promsic mode

among other things added a function called ixgbe_vlan_filter_enable.
This new function wants to access and set some rx_ring parameters, but
adapter->rx_ring has already been freed.  This simply moves the free
until after the access and makes __ixgbe_shutdown look more like
ixgbe_remove.
