vhost/net: discard IOTLB when ACCESS_PLATFORM is cleared
Apply the common device IOTLB teardown when userspace clears
VIRTIO_F_ACCESS_PLATFORM. This drops stale translations and avoids
rebuilding an existing IOTLB during feature updates that keep
ACCESS_PLATFORM enabled.
The transition invalidates cached vring access even with an attached
backend. The backend remains attached, but userspace must configure the
vring addresses for the new address mode after a successful live
transition.
Fixes: 6b1e6cc7855b ("vhost: new device IOTLB API")
