Any chance you can apply following patch and check output for correct
and broken cases (it will produce 2 or 3 debug strings for each crypto
operation)?

Ouch, forgot idx++;
Unfortunately I'm unable to boot current -git, this time it
hangs while trying to mount dm-crypt devices. The last output
I get is:

I'll try to narrow it down.
BTW, I also get this just before the HIFN debug output:
[ 14.695659] device-mapper: uevent: version 1.0.3
[ 14.697257] device-mapper: ioctl: 4.13.0-ioctl (2007-10-18)

[ 15.137123] device-mapper: crypt: Selected cipher does not support IVs
Not sure if its related, but I don't get this when using software
crypto.
