HFP: move sco sm to OPENNING only if initiate SCO connection to peer (2/2)

If peer device is not active device, bta_ag_create_sco will not initate
sco connection to peer, but return directly. As a result, bta ag sco or
bta twsp sco SM will block in OPENNING state. To avoid this issue, move
sco sm to OPENNING only if initate SCO connection to peer.
