PCI: shpchp: Handle push button event asynchronously
Use non-ordered workqueue for attention button events. Attention button events on each slot can be handled asynchronously. So we should use non-ordered workqueue. This patch also removes ordered workqueue in shpchp as a result. 486b10b ("PCI: pciehp: Handle push button event asynchronously") made the same change to pciehp. I split this out from a patch by Yijing Wang <wangyijing@huawei.com> so we fix one thing at a time and to make the shpchp history correspond more closely with the pciehp history.
