When the PCI device is surprise removed, requests may not complete
the device as the VQ is marked as broken. Due to this, the disk

An alternative of IO timeout has been considered, however
when the driver knows about unresponsive block device, swiftly clearing
them enables users and upper layers to react quickly.
Verified with multiple device unplug iterations with pending requests in
virtio used ring and some pending with the device.
