That avoids delays between WR post and HW response. If the template API was activated, PMD will use control queue for sync operations. 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 template API environment.
