    vlan: Fix vlan-in-vlan crashes.
    
    As analyzed by Patrick McHardy, vlan needs to reset it's
    netdev_ops pointer in it's ->init() function but this
    leaves the compat method pointers stale.
    
    Add a netdev_resync_ops() and call it from the vlan code.
    
    Any other driver which changes ->netdev_ops after register_netdevice()
    will need to call this new function after doing so too.
    
    With help from Patrick McHardy.
