iavf: schedule a request immediately after add/delete vlan

Browse Source 
[ 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.
