Jason Wang 0cf33fb6b4 virtio-net: correctly drop truncated packets 
When packet is truncated during receiving, we drop the packets but
neither discard the descriptor nor add and signal used
descriptor. This will lead several issues:

- sg mappings are leaked
- rx will be stalled if a lots of packets were truncated

In order to be consistent with vhost, fix by discarding the descriptor
in this case.
