[dpdk-dev] [PATCH 2/2] ethdev: fix metadata documentation

[Dekel Peled <dekelp@mellanox.com>]

Previous patch introduced the Tx metadata feature, with unnecessary
restrictions on data entry.

This fix updates the documentation, removing the data entry
restrictions on metadata item.

Fixes: aa0b9484eb5f ("ethdev: support metadata as flow rule criteria")
