openssl speed fails to count for aead decryption

[niyazmurshed]

Hi,
I have recently started using version (OpenSSL 3.3.0-dev) where I am looking at aead encryption and decryption.
It seems that something has been broken in decryption. Has something changed from previous version?
I don't see any change in speed.c that might have caused this.

This is regression from 98283a6

@beldmit Unfortunately when decrypting we cannot really check the result of the final calls. We would have to use real data and not something fictious.

@t8m we can expect failure instead of success in case of decrypt, I think. Or honestly do encryption first...
