sched,mmc: 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.
In this case, use fifo_low, because it only cares about being above
SCHED_NORMAL. Effectively no change in behaviour.
