Subject: [PATCH bpf-next] selftests/bpf: fix compiler warning in BPF_KPROBE definition in loop6.c
Add missing return type to BPF_KPROBE definition. Without it, compiler
generates the following warning:
progs/loop6.c:68:12: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
BPF_KPROBE(trace_virtqueue_add_sgs, void *unused, struct scatterlist **sgs,
^
1 warning generated.
Fixes: 86a35af628e5 ("selftests/bpf: Add a verifier scale test with unknown bounded loop")
