[PATCH] virtio-net: Avoid indirection_table_mask overflow

We computes indirections_len by adding 1 to indirection_table_mask, but it may overflow indirection_table_mask is UINT16_MAX. Check if indirection_table_mask is small enough before adding 1. Fixes: 590790297c0d ("virtio-net: implement RSS configuration command") Signed-off-by: Akihiko Odaki ---
