crypto: engine - Reduce default RT priority

The crypto engine initializes its kworker thread to FIFO-99 (when
requesting RT priority), reduce this to FIFO-50.

FIFO-99 is the very highest priority available to SCHED_FIFO and
it not a suitable default; it would indicate the crypto work is the
most important work on the machine.
