libpayload: usb: Fix several minor USB stack bugs

This patch fixes the following minor bugs in the USB stack:

1. Ensure that all dynamically allocated device structures are cleaned
    on detachment, and that the device address is correctly released again.
    2. Make sure MSC and HID drivers notice missing endpoints and actually
    detach the device in that case (to prevent it from being used).
    3. Make sure XHCI-specific set_address() cleans up all data structures
    on failure.
    4. Fix broken Slot ID range check that prevented XHCI devices from being
    correctly cleaned up.
