RSS support for L2 non-ip packets is missing in previous versions.

However, due to code refactor, the fix [1] in main branch cannot
be applied directly. This patch fixes this issue in stable versions.

[1] https://patchwork.dpdk.org/patch/94066/

Fixes: 5ad3db8d4bdd ("net/ice: enable advanced RSS")
