[PATCH BlueZ 2/4] android/A2DP: Use avdtp_add_disconnect_cb to cleanup on disconnect

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This replaces the use of g_io_add_watch with avdtp_add_disconnect_cb so
connection tracking stay within AVDTP code.
