Higher layers call this function to set the idle timeout for a fixed channel.
The "idle timeout" is the amount of time that a connection can remain up with no L2CAP channels on it. A timeout of zero means that the connection will be torn down immediately when the last channel is removed. A timeout of 0xFFFF means no timeout. Values are in seconds. A bd_addr is the remote BD address. If bd_addr = BT_BD_ANY, then the idle timeouts for all active l2cap links will be changed.
