w1: add a scheduling point to the slave search
sgi_w1 busy-waits through each time slot and has no triplet operation,
so one 64-bit search pass holds the CPU for more than 20 ms. Without
full preemption that delays every task woken meanwhile on a single CPU,
enough to underrun an audio ring while the bus is searched.
Call cond_resched() once per triplet.
