virtio-net: fix the vq coalescing setting for vq resize

According to the definition of virtqueue coalescing spec[1]:

  Upon disabling and re-enabling a transmit virtqueue, the device MUST set
  the coalescing parameters of the virtqueue to those configured through the
  VIRTIO_NET_CTRL_NOTF_COAL_TX_SET command, or, if the driver did not set
  any TX coalescing parameters, to 0.

  Upon disabling and re-enabling a receive virtqueue, the device MUST set
  the coalescing parameters of the virtqueue to those configured through the
  VIRTIO_NET_CTRL_NOTF_COAL_RX_SET command, or, if the driver did not set
  any RX coalescing parameters, to 0.

We need to add this setting for vq resize (ethtool -G) where vq_reset happens.
