workqueue: clear POOL_DISASSOCIATED in rebind_workers()
a9ab775bcadf ("workqueue: directly restore CPU affinity of workers
from CPU_ONLINE") moved pool locking into rebind_workers() but left
"pool->flags &= ~POOL_DISASSOCIATED" in workqueue_cpu_up_callback().
There is nothing necessarily wrong with it, but there is no benefit
either. Let's move it into rebind_workers() and achieve the following
benefits:
1) better readability, POOL_DISASSOCIATED is cleared in rebind_workers()
as expected.
2) we can guarantee that, when POOL_DISASSOCIATED is clear, the
running workers of the pool are on the local CPU (pool->cpu).
