selftests/bpf: do not pass NULL for non-nullable params in dummy_st_ops
dummy_st_ops.test_2 and dummy_st_ops.test_sleepable do not have their
'state' parameter marked as nullable. Update dummy_st_ops.c to avoid
passing NULL for such parameters, as the next patch would allow kernel
to enforce this restriction.
