bluetooth: Fix premature acquire attempts

A transport should be considered connected only after the connection
procedure is complete, as expressed in audio_state_to_transport_state().

module-bluetooth-device should be loaded only after at least one
transport is not only created (during configuration), but also
connected.

This fixes the issue of premature acquire attempts sometimes experienced
when a headset is connected (issue not present in v3.0 though).
