vxge: hotplug stall 

When hot-unplugging a vxge adapter while running, the driver's remove
routine prints warning and then stalls the calling thread.  This is due
to vxge_remove calling vxge_device_unregister to unregister the netdev
before calling flush_scheduled_work clear any pending work.  Swapping
the order of these two functions resolves the issue.
