[EXT] [PATCH] crypto/scheduler: fix session retrieval for ops

[Akhil Goyal]

> In cases where some ops failed to enqueue, the op session was never being
> reset. This resulted in a segmentation fault when processing ops the
> next time. To fix this, only set the op session after the failure
> condition is checked.
> 
> Also, the incorrect ops index was being used for session retrieval when
> dequeueing for the secondary worker.
> 
> Fixes: 6812b9bf470e ("crypto/scheduler: use unified session")
