vhost: check header for legacy dequeue offload

When parsing the virtio net header and packet header for dequeue offload,
we need to perform sanity check on the packet header to ensure:
  - No out-of-boundary memory access.
  - The packet header and virtio_net header are valid and aligned.

Fixes: d0cf91303d73 ("vhost: add Tx offload capabilities")
