Tycho Andersen (AMD) 4479884d1f perf lock contention: fix segfault in lock contention -b/--use-bpf 
When run on a kernel without BTF info, perf crashes:

    libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled?
    libbpf: failed to find valid kernel BTF

    Program received signal SIGSEGV, Segmentation fault.

Check if btf loading failed, and don't do anything with it in
init_numa_data(). This leads to the following error message, instead of
just a crash:

    libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled?
    libbpf: failed to find valid kernel BTF
    libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled?
    libbpf: failed to find valid kernel BTF
    libbpf: Error loading vmlinux BTF: -ESRCH
    libbpf: failed to load BPF skeleton 'lock_contention_bpf': -ESRCH
    Failed to load lock-contention BPF skeleton
    lock contention BPF setup failed
