speed: Pass IV to EVP_CipherInit_ex for -evp runs with non-AEAD ciphers

Some (non-AEAD) ciphers require an IV to be used. Always pass a (dummy) IV
when setting the key. It is ignored by ciphers that do not use an IV.

Commit 607a46d003 corrected the use of AEAD
ciphers, but removed the IV from being passed to EVP_CipherInit_ex() for
non-AEAD ciphers.

Fixes: 607a46d003
