[PATCH net] bpf, test_verifier: fix a test case error result on unprivileged

[Daniel Borkmann]

Running ./test_verifier as unprivileged lets 1 out of 98 tests fail:

  [...]
  #71 unpriv: check that printk is disallowed FAIL
  Unexpected error message!
  0: (7a) *(u64 *)(r10 -8) = 0
  1: (bf) r1 = r10
  2: (07) r1 += -8
  3: (b7) r2 = 8
  4: (bf) r3 = r1
  5: (85) call bpf_trace_printk#6
  unknown func bpf_trace_printk#6
  [...]

The test case is correct, just that the error outcome changed with
ebb676daa1a3 ("bpf: Print function name in addition to function id").
Same as with e00c7b216f34 ("bpf: fix multiple issues in selftest suite
and samples") issue 2), so just fix up the function name.

Fixes: ebb676daa1a3 ("bpf: Print function name in addition to function id")
