[PATCH] perf bpf filter: Fix a broken perf sample data naming in BPF

[Namhyung Kim]

BPF CO-RE requires 3 underscores for the ignored suffix rule but it
mistakenly used only 2.  Let's fix it.

Fixes: 3a8b8fc31748 ("perf bpf filter: Support pre-5.16 kernels where 'mem_hops' isn't in 'union perf_mem_data_src'")
