workqueue: split kick_pool() into kick_pool_pick()

Browse source

Factor the worker selection out of kick_pool() into kick_pool_pick(),
which picks and claims the worker under pool->lock but, instead of waking
it, returns the worker's task via an out-param so the caller can issue
the wakeup after dropping pool->lock. BH kicks and wake_cpu setup still
happen under the lock.

kick_pool() becomes a thin wrapper that wakes the returned task, so all
existing callers keep waking under pool->lock.

Pure refactor, no functional change.
