Bluetooth: Fix the issue that peer A2DP SNK device can not auto-reconnect.

If peer A2DP SNK disconnected by some reason, the device will reject reconnection request from peer.
This CL will judge the peer device is A2DP SRC, will reject the reconnection request.
So if peer device is A2DP SNK, will accept the reconnection request.
