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.
