Revert "virtio_pci: Support surprise removal of virtio pci device"
This reverts commit 43bb40c5b92659966bdf4bfe584fde0a3575a049.
Marking the device as broken will cause the uncompleted IO request on
virtio-blk since virtblk_done will not continue when it find the broken virtqueu
at last it will cause the failure of removal of virtio-blk device because of
uncompleted IO request
The correct fix for the issue that commit 43bb40c5b9 ("virtio_pci:
Support surprise removal of virtio pci device") tried to fix
is that virtio backend always complete the IO request as soon as possible
