Martin KaFai Lau 280de43e88 bpf: Remove ipv6_bpf_stub usage in test_run ...

bpf_prog_test_run_skb() uses net->ipv6.ip6_null_entry for
BPF_PROG_TYPE_LWT_XMIT test runs.

It currently checks ipv6_bpf_stub before using ip6_null_entry.
ipv6_bpf_stub will be removed by the CONFIG_IPV6=m support removal
series posted at [1], so switch this check to ipv6_mod_enabled()
instead.

This change depends on that series [1]. Without it, CONFIG_IPV6=m is
still possible, and net->ipv6.ip6_null_entry remains NULL until
the IPv6 module is loaded.
