[PATCH] virtio_vdpa: Support surprise removal of virtio vdpa device

From: dongsheng li
Date: Mon Jan 10 2022 - 23:09:02 EST


When virtio vdpa device removed, the abnormal damage of the device cannot be
perceived normally, which will cause problems similar to:

Commit 43bb40c5b926 ("virtio_pci: Support surprise removal of
virtio pci device")

Hence, add the ability to abort the command on surprise removal
