Kristof Provost 3fcb1aaef1 vtnet: fix panic on unload ... Since r276367 added the virtio_mmio support vtnet_modevent() gets called twice. This resulted in a memory leak during load and a panic on unload. Count the loads so we only initialise once (just like cxgbe(4)), and only clean up in the final unload.
