When executing suspend to ram, if lacking the operations to reset device and free unused buffers before deleting a vq, resource leaks and inconsistent device status will appear. According to chapter "3.3.1 Driver Requirements: Device Cleanup:" of virtio-specification: Driver MUST ensure a virtqueue isn’t live (by device reset) before removing exposed buffers. Therefore, modify the virtinput_freeze function to reset the device and delete the unused buffers before deleting the virtqueue, just like virtinput_remove does.
