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.
