In its current form, we cannot test multiple simultaneous crypto sessions with 
tcrypt.
Crypto offload hardware accelerators are usually capable of handling multiple 
session in parallel.
This patch allows to load such hardware.
Even if offload accelerators are not present, multiple crypto sessions can 
execute in parallel on Multicore.

Based on kernel scheduling of threads, this change can make tcrypt give varying 
results in different runs.
For consistent results, we can use existing synchronous mode crypto sessions.
