loops/avirt: forget saved loops after creation

avirt needs a backup of loops, before creating the streams.
However, this breaks software dynamic streams such as those of
of type bluez-alsa, because the logic was re-calling the loop creation
at each call of the 'attach' verb.
The fix simply consists in forgetting the saved loops once they are created
