staging: rtl8192e: Remove create_workqueue()
With conccurency managed workqueues, use of dedicated workqueues can
be replaced by system_wq. Drop wq by using system_wq.
Since there are multiple work items per rtllib but they do not need to
be ordered, increase of concurrency by switching to system_wq should
not break anything.
All work items are sync canceled on rtllib_stop_protocol() so it is
guaranteed that no work is running when rtl92e_disable/reset/restart
functions are called.
