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. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S. Miller <davem@davemloft.net>
