[PATCH bpf-next] samples: bpf: avoid name collision with kernel enum values

[Kumar Kartikeya Dwivedi <memxor@xxxxxxxxx>]

In xdp_redirect_map_multi.bpf.c, on newer kernels samples compilation
fails when vmlinux.h is generated from a kernel supporting broadcast for
devmap. Hence, avoid naming collisions to prevent build failure.

Fixes: a29b3ca17ee6 (samples: bpf: Convert xdp_redirect_map_multi_kern.o to XDP samples helper)
