FYI this test doesn't use dmcrypt at all, only kernel crypto API, so it
depends how crypto layer module processes it.

Anyway, it doesn't matter here - the whole test basically runs encryption
of 1MB buffer over userspace API to kernel crypto layer.

It cannot take so long - it is clear problem somewhere.
