shpchp: update workqueue usage
* Rename shpchp_wq to shpchp_ordered_wq and add non-ordered shpchp_wq
which is used instead of the system workqueue. This is to remove
the use of flush_scheduled_work() which is deprecated and scheduled
for removal.
* With cmwq in place, there's no point in creating workqueues lazily.
Create both shpchp_wq and shpchp_ordered_wq upfront.
* Include workqueue.h from shpchp.h.
