ixgbe: fix panic when shutting down system with WoL enabled

Browse Source 
This patch added to 2.6.34:

	commit 5f6c018199

	    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.
