[issue1638] OpenSSL cryptodev patch

[Thomas Nikolajsen (via DragonFly issue tracker)]

hifn(4) works with this patch.
cryptotest works, and 'openssl enc' also doesn't have plaintext in encoded text.
There is problem: LINT build fails.
Also if hifn(4) is unloaded, then loading it again fails, with message below.

I did hifn(4) test on both amd64 system (only i386; will do x86_64 test),
and on low mem system, soekris 4801 w/ vpn1411 (same pciconf output as vpn1401).

I also did padlock(4) test on Via C7 system, and got same result as below:
'openssl enc' using cipher supported by cryptodev contains plaintext.
This is not the case when using 'openssl enc -engine padlock'.
