workqueue: clear POOL_DISASSOCIATED in rebind_workers()
The commit a9ab775bcadf ("workqueue: directly restore CPU affinity of
workers from CPU_ONLINE") moved the pool->lock into rebind_workers()
without also moving "pool->flags &= ~POOL_DISASSOCIATED".
There is nothing wrong with "pool->flags &= ~POOL_DISASSOCIATED" not
being moved together, but there isn't any benefit either. We move it
into rebind_workers() and achieve these benefits:
1) Better readability. POOL_DISASSOCIATED is cleared in
rebind_workers() as expected.
2) When POOL_DISASSOCIATED is cleared, we can ensure that all the
running workers of the pool are on the local CPU (pool->cpu).
