[PATCH] net/mlx5: fix PMD compilation in non-HWS setup

[Gregory Etelson]

The PMD calls `mlx5_hw_ctx_validate()` function to differentiate
between HWS and SWS run-time setups.

The function was not defined if HWS functionality was not enabled
during meson code configuration.

The patch creates default weak mlx5_hw_ctx_validate symbol.

Fixes: d3144c59ac98 ("net/mlx5: validate HWS context in meter operations")
