perf test bpf: Improve message about expected samples
When failing on one of the BPF tests we were just stating:
BPF filter result incorrect
Add some more info to help figuring out the problem:
BPF filter result incorrect, expected 56, got 0 samples
This came out while investigating this failure, first seen after
updating the kernel to the 4.15.0-rc6 tag:
[root@jouet ~]# perf test bpf
39: BPF filter :
39.1: Basic BPF filtering : FAILED!
39.2: BPF pinning : Skip
39.3: BPF prologue generation: Skip
39.4: BPF relocation checker : Skip
