usb: xhci: Fix vendor command error if the request type is USB_REQ_SET_ADDRESS or...

Add test into xhci_submit_control_message for usb requesttype in USB
vendor request being of standardized type. This fixes detection of
certain USB fixes, for example Ethernet, USB 3.0 port. Non standardized
requesttype in USB vendor request will be ignored.
