    iavf: schedule a request immediately after add/delete vlan
    
    [ Upstream commit 5f3d319a248654a805bafc9e7094bcea47dac6c7 ]
    
    When the iavf driver wants to reconfigure the VLAN filters
    (iavf_add_vlan, iavf_del_vlan), it sets a flag in
    aq_required:
      adapter->aq_required |= IAVF_FLAG_AQ_ADD_VLAN_FILTER;
    or:
      adapter->aq_required |= IAVF_FLAG_AQ_DEL_VLAN_FILTER;
    
    This is later processed by the watchdog_task, but it runs periodically
    every 2 seconds, so it can be a long time before it processes the request.
    
    In the worst case, the interface is unable to receive traffic for more
    than 2 seconds for no objective reason.
