[PATCH] net/mlx5: fix missing next proto in IPv4/6 encap hash calc

[Maayan Kashani]

Add missing memcpy for next_protocol field when processing IPv4/6 items
in flow_hw_calc_encap_hash function. This ensures the IPv4/6 header's
proto field is properly copied to the hash calculation data structure.

Fixes: bb328f44afe9 ("net/mlx5: support encapsulation hash calculation")
