[dpdk-dev] [PATCH] net/mlx5: remove redundant size calculation macro

[Dekel Peled <dekelp@mellanox.com>]

Patch [1] added, among other definitions, the macro MLX5_ST_SZ_DB.
Patch [2] added later the macro MLX5_ST_SZ_BYTES, which is exactly
the same macro with a different name.
Each of these macros was used in very few places.

This patch removes the definition of MLX5_ST_SZ_DB, and replaces it
with MLX5_ST_SZ_BYTES wherever it was used.
Macro MLX5_ST_SZ_BYTES was preffered since it is the same macro
name used in kernel code, see [3].
