Ctrlq in polling mode may cause the virtual machine to hang and
occupy additional CPU resources. Enabling the irq for ctrlq
alleviates this problem and allows commands to be requested
concurrently.

Changelog
=========
v1->v2:
  - Refactor the patch 1 and rephase the commit log.

Heng Qi (2):
  virtio_net: enable irq for the control vq
