[PATCH v1] net/mlx5: fix meter policy creation assert

[Shun Hao <shunh@nvidia.com>]

The meter policy creation doesn't belong to RTE flow creation
process, so thread workspace was not initialized and there will be
assert error when using it.

This patch removes the incorrect using of thread workspace in meter
policy creation, and adds a flag in policy instead. When creating
RTE flow, can use the flag to set the mark flag in thread workspace.

Fixes: 082becbf1f35 ("net/mlx5: fix mark enabling for Rx")
