Re: [PATCH] qemu_process: Skip over non-virtio NIC models when refreshing rx-filter

After guest is started, or we are reconnecting to already running one (after daemon restart), qemuProcessRefreshRxFilters() is called to refresh rx-filters (basically MAC addresses of guest NICs) as they might have changed while we were not running (for the case when reconnecting to an already running guest), or we need to enable them by running a command (for freshly started guest - see processNicRxFilterChangedEvent()). Now, our XML parser allowed trustGuestRxFilters attribute for all types and models of <interface/> while in reality, only virtio model can see MAC address changes.
