vmxnet3: Do not fill stats if device is inactive
Guest OS may issue VMXNET3_CMD_GET_STATS even before device was activated (for example in linux, after insmod but prior net-dev open). Accessing shared descriptors prior device activation is illegal as the VMXNET3State structures have not been fully initialized. As a result, guest memory gets corrupted and may lead to guest OS crashes. Fix, by not filling the stats descriptors if device is inactive.
