crypto: atmel-aes - fix the keys zeroing on errors 

[ Upstream commit 5d804a5157 ]

The Atmel AES driver uses memzero_explicit on the keys on error, but the
variable zeroed isn't the right one because of a typo. Fix this by using
the right variable.

Fixes: 89a82ef87e ("crypto: atmel-authenc - add support to authenc(hmac(shaX), Y(aes)) modes")
