samples/bpf: fix a compilation failure
[ Upstream commit 534e0e52bc23de588e81b5a6f75e10c8c4b189fc ] samples/bpf build failed with the following errors: $ make samples/bpf/ ... HOSTCC samples/bpf/sockex3_user.o /data/users/yhs/work/net-next/samples/bpf/sockex3_user.c:16:8: error: redefinition of ‘struct bpf_flow_keys’ struct bpf_flow_keys { ^ In file included from /data/users/yhs/work/net-next/samples/bpf/sockex3_user.c:4:0: ./usr/include/linux/bpf.h:2338:9: note: originally defined here struct bpf_flow_keys *flow_keys; ^ 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.
