test/crypto: fix check for OOP header data

[ upstream commit 27eb74ea6e25966d3857539cb15ddd4f20f05ebe ]

The data of the out-of-place header is never checked. Therefore, the faulty PMD, which overwrites this data, will not be able to verify that with tests. New checks to support that were added to the GCM OOP functions.

Fixes 51e202f0596f ("test/crypto: rename GCM test code")
