net/mlx5: fix meter table definitions

As metering and metadata features were developed at the same time. The
metering and metadata tables are defined conflicted.

This cause the meter suffix flow jump to the same metadata table and
cause flow deadloop.

Adjust the metering table define to fix that issue.
