usb: fix ->update_hub_device() vs hdev->maxchild

Commit d8521afe3586 "usb: assign default peer ports for root hubs"
delayed marking a hub valid (set hdev->maxchild) until it had been fully
configured and to enable the publishing of valid hubs to be serialized
by usb_port_peer_mutex.

However, xhci_update_hub_device() in some cases depends on
hdev->maxchild already being set.  Do the minimal fix and move it after
the setting of hdev->maxchild.
