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

commit 24775ac2fe68132d3e0e7cd3a0521ccb1a5d7243 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: 48fe583fe541 ("crypto: amlogic - Add crypto accelerator for amlogic GXL")
