workqueue: Improve locking rule description for worker fields
* Some worker fields are modified only by the worker itself while holding
pool->lock thus making them safe to read from self, IRQ context if the CPU
is running the worker or while holding pool->lock. Add 'K' locking rule
for them.
* worker->sleeping is currently marked "None" which isn't very descriptive.
It's used only by the worker itself. Add 'S' locking rule for it.
A future patch will depend on the 'K' rule to access worker->current_* from
the scheduler ticks.
