> Synchronous calls for meter ASO try to pull pending completions from CQ,

> response.
> If the template API was activated, PMD will use control queue for sync

> 
> PMD has different formats for the `user_data` context in sync and async meter
> ASO calls.
> PMD port destruction procedure submits async operations to the port control
> queue and polls the queue CQs to clean HW responses.
> 
> Port destruction can pull a meter ASO completion from control CQ.
> Such completion has sync format, but was processed by async handler.

> The patch implements sync meter ASO interface with async calls in the
