workqueue: restructure __alloc_workqueue_key()

* Move initialization and linking of pool_workqueues into
  init_and_link_pwq().

* Make the failure path use destroy_workqueue() once pool_workqueue
  initialization succeeds.

These changes are to prepare for dynamic management of pool_workqueues
and don't introduce any functional changes.

While at it, convert list_del(&wq->list) to list_del_init() as a
precaution as scheduled changes will make destruction more complex.
