Operations on a crytpodev are considered as *write* only, the callback
of read direction is never invoked. Use NULL instead of an unreachable
path(cryptodev_backend_throttle_timer_cb on read direction).

would be nice to explain in the same comment in the code what exactly 
needs fixing, and why it isn‘t being fixed at this point.
