crypto: ixp4xx - Fix error handling path in 'aead_perform()'
commit 28389575a8cf933a5f3c378556b9f4d3cce0efd2 upstream. In commit 0f987e25cb8a, the source processing has been moved in front of the destination processing, but the error handling path has not been modified accordingly. Free resources in the correct order to avoid some leaks.
