vmxnet3: prevent div-by-zero panic when ring resizing uninitialized dev
Linux is free to call ethtool ops as soon as a netdev exists when probe finishes. However, we only allocate vmxnet3 tx/rx queues and initialize the rx_buf_per_pkt field in struct vmxnet3_adapter when the interface is opened (UP).
