net/mlx5: Add SPF function type for page management

Add MLX5_SPF to enum mlx5_func_type so SPFs get their own page counter,
and add the corresponding WARN check at page cleanup. Wait for SPF pages
to be reclaimed during ECPF teardown, alongside the existing host PF and
VF page waits.

SPF page requests are always identified by vhca_id, so the legacy
func_id_to_type() path is not reached for satellite PFs.
