[issue1748] bpf_validate() uses BPF_RVAL() when it should use BPF_SRC()

["Sascha Wildner \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

Sascha Wildner <saw@online.de> added the comment:

OpenBSD has changed this to BPF_SRC() based on a report by Guy. NetBSD still
uses BPF_RVAL (couldn't find a PR either), while FreeBSD uses this:

/*
 * Check for constant division by 0.
 */
if (p->code == (BPF_ALU|BPF_DIV|BPF_K) && p->k == 0)
        return (0);
