Subject[PATCH v2] Bluetooth: virtio_bt: fix memory leak in virtbt_rx_handle()
Date
On the reception of packets with an invalid packet type, the memory of
the allocated socket buffers is never freed. Add a default case that frees
these to avoid a memory leak.

Changes in v2:
- Add break; to default case
