virtio_pci: support VIRTIO_F_RING_RESET
This patch implements virtio pci support for QUEUE RESET.
Performing reset on a queue is divided into these steps:
1. notify the device to reset the queue
2. recycle the buffer submitted
3. reset the vring (may re-alloc)
4. mmap vring to device, and enable the queue
This patch implements virtio_reset_vq(), virtio_enable_resetq() in the
pci scenario.
