virtio: struct virtio_config_ops add callbacks for queue_reset
reset can be divided into the following four steps (example):
1. transport: notify the device to reset the queue
2. vring: recycle the buffer submitted
3. vring: reset/resize the vring (may re-alloc)
4. transport: mmap vring to device, and enable the queue
In order to support queue reset, add two callbacks in struct
virtio_config_ops to implement steps 1 and 4.
