Fix avdtp not start

[Root Cause]
When acp connect from peer, the pscb will use the wrong handle
 which maybe used by another peer, and then the BTA_AV_SST will
 be used by two pscb handle by the same current peer, and finally
 local cannot send start_req as the BTA_AV_SST state wrong. And
no sound output from the peer device.

[Solution]
Fix bta av layer pscb donot match with btif av layer btifavpeer
