sched,crypto: Convert to sched_set_fifo*()
Because SCHED_FIFO is a broken scheduler model (see previous patches) take away the priority field, the kernel can't possibly make an informed decision. Use sched_set_fifo() to request SCHED_FIFO and delegate actual priority selection to userspace. Effectively no change in behaviour.
