make[3]: *** [samples/bpf/sockex3_user.o] Error 1
Commit d58e468b1112d ("flow_dissector: implements flow dissector BPF hook")
introduced struct bpf_flow_keys in include/uapi/linux/bpf.h and hence
caused the naming conflict with samples/bpf/sockex3_user.c.
The fix is to rename struct bpf_flow_keys in samples/bpf/sockex3_user.c
to flow_keys to avoid the conflict.
