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
Fixes: 4b04e0decd25 ("perf test: Fix basic bpf filtering test")

Hi Arnaldo, please have a look.
This is still valid.
Thanks.
