crypto: atmel-aes - Reestablish the correct tfm context at dequeue
[ Upstream commit 6d48de655917a9d782953eba65de4e3db593ddf0 ]
In case there were more requests from different tfms in the crypto
queue, only the context of the last initialized tfm was considered.
Fixes: ec2088b66f7a ("crypto: atmel-aes - Allocate aes dev at tfm init time")
