vhost: do not try to access device IOTLB when not initialized
The code will try to access dev->iotlb when processing
VHOST_IOTLB_INVALIDATE even if it was not initialized which may lead
to NULL pointer dereference. Fixes this by check dev->iotlb before.
Fixes: 6b1e6cc7855b0 ("vhost: new device IOTLB API")
