usbip: remove kernel addresses from usb device and urb debug msgs
usbip_dump_usb_device() and usbip_dump_urb() print kernel addresses.
Remove kernel addresses from usb device and urb debug msgs and improve
the message content.
Instead of printing parent device and bus addresses, print parent device
and bus names.
