Subject: [PATCH 1/1] workqueue: Remove redundant assignment

From: Adrian Huang <ahuang12@...ovo.com>

The member 'node' of worker_pool struct (per_cpu worker_pool) is
assigned in workqueue_init_early() and workqueue_init().
Commit 2186d9f940b6 ("workqueue: move wq_numa_init() to workqueue_init()")
fixes an issue by moving wq_numa_init() to workqueue_init() in order
to get the valid 'cpu to node' mapping. So, remove the redundant
assignment in workqueue_init_early().
