perf header: Fix one memory leakage in process_bpf_btf()
If __perf_env__insert_btf() returns false due to a duplicate btf node
insertion, the temporary node will leak. Add a check to ensure the memory
is freed if the function returns false.
Fixes: a70a1123174ab592 ("perf bpf: Save BTF information as headers to perf.data")
