#71 unpriv: check that printk is disallowed FAIL
Unexpected error message!

The test case is correct, just that the error outcome changed with
ebb676daa1 ("bpf: Print function name in addition to function id").
Same as with e00c7b216f ("bpf: fix multiple issues in selftest suite
and samples") issue 2), so just fix up the function name.
Fixes: ebb676daa1 ("bpf: Print function name in addition to function id")
