openssl: add fix for hash cryptodev offloading

See http://rt.openssl.org/Ticket/Display.html?id=2770&user=guest&pass=guest
This has been sitting for ages in the openssl tracker and it's verified
to cause issues.
The patch only touches cryptodev engine offloading so it's pretty safe.
Tested on CAAM SEC4 hardware.
