[v2 04/16] net/mlx5/hws: remove unused capabilities and fields

[Itamar Gozlan <igozlan@nvidia.com>]

From: Yevgeny Kliteynik <kliteyn@nvidia.com>

The following caps were never in use:
 - wire_regc
 - metadata_c
 - metadata_c_mask
Also send ring's reg_addr field wasn't in use.

Removing these caps and fields from structs and removing
the code that queried them.
