audio_policy: Null check for output profile types

- Currently invalidated Deep buffer and offload
tracks are not suspended/closed.
- BT output is not setting profile type. While initiating voice
call, APM closes all opened outputs to fall back to ULL, based
on profile types
- Modify the check to ensure that valid OutputDesc are
suspended/closed.
