policy_hal: fix CTS concurrent audio playback

 -fall back to non-direct output is not working for 3rd playback request
  when both compress offload and direct pcm are in use as only one flag is
  set to true due to break statement.
 -Remove break statement to set both flags to true when both compress offload
  and direct pcm are in use.
