[PATCH 24.11] net/mlx5: fix item prepending conditions

[Dariusz Sosnowski]

Offending commit, which is a backport, dropped checks
on priv->sh->config.repr_matching before flow pattern is prepended
inside mlx5 driver. This issue was caused by the fact,
that on main branch this config flag does not exist anymore.
priv->sh->config.repr_matching was removed in 25.11 release.
It should be used in 24.11 branch.
This patch adds back the missing check.

Fixes: 471350f6cd46 ("net/mlx5: prepend implicit items in sync flow creation")
