The return value was not being checked when calling the
get_writeback_data function in the AES test case. On failure, this led
to a NULL dereference when using memcpy later. The return value is now
checked to avoid this NULL dereference.

Coverity issue: 363463

I'd rather flag:
Fixes: 952e10cdad5e ("examples/fips_validation: support scatter gather list")

Can you double check?

And I think we have the same issue in fips_mct_sha_test().

to a NULL dereference when using memcpy later. The return value is now
