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.
