This reverts commit 43bb40c5b926 ("virtio_pci: Support surprise removal of
virtio pci device").
The cited commit introduced a fix that marks the device as broken
during surprise removal. However, this approach causes uncompleted
I/O requests on virtio-blk device. The presence of uncompleted I/O
requests prevents the successful removal of virtio-blk devices.
This fix allows devices that simulate a surprise removal but actually
remove gracefully to continue working as before.
For surprise removals, a better solution will be preferred in the future.
