> In the metadata flow split, PMD created the prefix subflow

> copy table jump actions. If the flow being split for metadata
> was the meter prefix subflow, the driver supposed to share the same
> meter split tag action for the metadata split flow. There was the wrong
> check for preceding meter split tag action, causing append with metadata
> split set tag action and resulting the meter suffix subflow was missed
> due to tag value mismatch.
> 
> This patch adds the checking before copying into extend action list,
> to make sure the correct shared tag is used.
