From: Corentin Labbe <clabbe.montjoie@gmail.com>

commit 7b3d853ead8187288bf99df38ed71ee02773a65f upstream.

Removing the driver cause an oops due to the fact we clean an extra
channel.
Let's give the right index to the cleaning function.
Fixes: f08fcced6d00 ("crypto: allwinner - Add sun8i-ss cryptographic offloader")
