workqueue: declare system_highpri_wq
system_highpri_wq is exported to modules via EXPORT_SYMBOL_GPL(), but it was forgotten to be declared in workqueue.h. So we add the declaration and a short description for it. tj: Minor comment tweak. Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Tejun Heo <tj@kernel.org>
