sched: Document memory barriers implied by sleep/wake-up primitives
Add a section to the memory barriers document to note the implied
memory barriers of sleep primitives (set_current_state() and wrappers)
and wake-up primitives (wake_up() and co.).
Also extend the in-code comments on the wake_up() functions to note
these implied barriers.
[ Impact: add documentation ]
