[PATCH bpf-next 6/7] selftests: bpf: fix test_kfunc_dynptr_param

[Puranjay Mohan <puranjay@kernel.org>]

As verifier now assumes that all kfuncs only takes trusted pointer
arguments, passing 0 (NULL) to a kfunc that doesn't mark the argument as
__nullable or __opt will be rejected with a failure message of: Possibly
NULL pointer passed to trusted arg<n>

Pass a non-null value to the kfunc to test the expected failure mode.
