leaudio: Fix reconnect after disconnected by Java

Disconnect from Java can happen in two cases
1.Profile connection timeout - this can happen on single device while
  other is connected
2. Intentional user disconnection - this will end up with all members
   being disconnected.

With this patch, if 1) happens, we want to be sure that device will get
back on allow list if other set members are connected
