Jason Wang 70e53e6e4d virtio-net: don't touch virtqueue if vm is stopped 
Guest state should not be touched if VM is stopped, unfortunately we
didn't check running state and tried to drain tx queue unconditionally
in virtio_net_set_status(). A crash was then noticed as a migration
destination when user type quit after virtqueue state is loaded but
before region cache is initialized. In this case,
virtio_net_drop_tx_queue_data() tries to access the uninitialized
region cache.

Fix this by only dropping tx queue data when vm is running.

Fixes: 283e2c2adc ("net: virtio-net discards TX data after link down")
