PCI: pciehp: Fix wrong workqueue cleanup
Fix improper workqueue cleanup. In the current pciehp, pcied_cleanup() calls destroy_workqueue() before calling pcie_port_service_unregister(). This causes kernel oops because flush_workqueue() is called in the pcie_port_service_unregister() code path after the workqueue was destroyed. So pcied_cleanup() must call pcie_port_service_unregister() first before calling destroy_workqueue().
