bpf: fix lb6 load balancing wrt ct_lookup6's ct_state
bpf: fix lb6 load balancing wrt ct_lookup6's ct_state

Commit bc703f5cb873 ("bpf: __ct_lookup() in forward direction must
pass in state ptr") tried to fix commit 3a8be7ebb16b ("bpf: don't
update ct_state on second v4 __ct_lookup") but added ct_state to
ct_lookup6() too much. The 2nd lookup had a NULL ct_state all the
time. Adding it broke the lb v6 parts, and bisect pointed to the
commit bc703f5cb873.
