[PATCH v2 10/10] net/virtio: fix Rx handler when checksum is requested

The simple Rx handler is selected even if Rx checksum offload is
requested by the application, but this handler does not support
offloads. This results in broken received packets (no checksum flag but
invalid checksum in the mbuf data).

Disable the simple Rx handler in that case.

Fixes: 96cb6711939e ("net/virtio: support Rx checksum offload")
