smsc911x: fix BUG if module is removed while interface is up
If the module is removed while its interface is up, smsc911x_stop is not
called until after smsc911x_drv_remove has disposed of phy_dev. This
patch changes the stop method to handle this situation.
This is a different problem to the one reported by dfoley@telus.net.
