  PMD implements sync METER flow action as async.
Queue selected for sync operations is `MLX5_HW_INV_QUEUE`.
That dummy queue value is translated into `CTRL_QUEUE_ID(priv)`.
Async job allocation converts INV queue into the real value, but
job release does not.

This patch fixes the queue value provided to `flow_hw_job_put()`.

This patch also removes dead code found in METER_MARK
destroy handler.

Coverity issue: 415806
Coverity issue: 415804
