xtalk: Caller passes xusb_spec to xusb_find_iface()

Browse Source 
* This xusb_spec:
  - Is a dummy struct used for this xusb instance only.
  - Is now passed by reference from caller.
  - So caller now manage the life cycle of this struct
* Also, demote one INFO() to DBG() (library should not print
  on its own)
* Also minor fix to DBG() output of spec initialization (leading 0)
