usb: Resolve warnings about unassigned bus on usb device creation

Browse Source 
When creating an USB device the old way, there is no way to specify the
target bus. Thus the warning issued by usb_create makes no sense and
rather confuses our users.

Resolve this by passing a bus reference to the usbdevice_init handler
and letting those handlers forward it to usb_create.
