Herbert Xu 50fdb78b7c crypto: seqiv - Do not use req->iv after crypto_aead_encrypt ...

As soon as crypto_aead_encrypt is called, the underlying request
may be freed by an asynchronous completion.  Thus dereferencing
req->iv after it returns is invalid.

Instead of checking req->iv against info, create a new variable
unaligned_info and use it for that purpose instead.
