The usb_sndaddr0pipe macro is only used in the hub_set_address function.
Replace it with usb_sndctrlpipe which provides the same functionality
but would also consider the endpoint device number.
If the device has not been initialised, it is safe to use
usb_sndctrlpipe in this context because udev->devnum is set to 0.
Therefore, this change does not affect behaviour, but reduces code
complexity by reusing the existing macro.
