perf test: Fix bpf test sample mismatch reporting

Browse Source 
commit 3e11300cdfd5f1bc13a05dfc6dccf69aca5dd1dc upstream.

When the expected sample count in the condition changed, the message
needs to be changed too, otherwise we'll get:

  0x1001f2091d8: mmap mask[0]:
  BPF filter result incorrect, expected 56, got 56 samples
