 Log Message:
 Pull up following revision(s) (requested by riastradh in ticket #565):

 	sys/dev/usb/usbnet.c: revision 1.32
 	sys/dev/usb/usbnet.c: revision 1.33
 
 Fix order of nulling un->un_pri->unp_ec.ec_mii.
 
 Can't null it until after if_detach prevents further use.
 
 While here, fix conditionals in usbnet_tick_task to use the unp_dying
 flag, not the nullness of mii (or of ifp, which never null because
 it's an embedded member).
 
 Fix inequality for refcnt drain: -1 here means all refs gone.
 
 Don't assume mii is not null here. Some drivers like urndis don't use
 mii, so they always have mii == NULL.
 ok riastradh. fixes PR kern/54762
