Subject: [PATCH net-next 09/10] ice: update VSI instead of init in some case

From: Michal Swiatkowski <michal.swiatkowski@...ux.intel.com>

ice_vsi_cfg() is called from different contexts:
1) VSI exsist in HW, but it is reconfigured, because of changing queues
   for example -> update instead of init should be used
2) VSI doesn't exsist, because rest has happened -> init command should
   be sent

To support both cases pass boolean value which will store information
what type of command has to be sent to HW.
