bpf samples: fix compiler errors with sockex2 and sockex3
These samples fail to compile as 'struct flow_keys' conflicts with definition in net/flow_dissector.h. Fix the same by renaming the structure used in the sample. Signed-off-by: Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
