Message:

libusb: Remove usb_iface_get_hc_handle_hub_child_impl.

Rename usb_iface_get_hc_handle_hub_impl ⇒ usb_iface_get_hc_handle_device_impl.
This was just a hidden duplicity, the only difference was using EXCHANGE_SERIALIZE instead of EXCHANGE_ATOMIC.
All USB devices, but root hubs, ask their parents for hc handle.
