[PATCH bpf-next] bpf: add struct bpf_redir_neigh forward declaration to BPF helper defs

[Andrii Nakryiko <andrii@xxxxxxxxxx>]

Forward-declare struct bpf_redir_neigh in bpf_helper_defs.h to avoid
compiler warning about unknown structs.

Fixes: ba452c9e996d ("bpf: Fix bpf_redirect_neigh helper api to support supplying nexthop")
