hs20 client compile problems on Fedora-26.

[Ben Greear]

On Fedora-26, the #else case is compiled in the code below, but there is no SKM_sk_num macro
existing in that version of openssl it seems.  Any idea what is a good fix for this?

Thanks,
Ben


static void add_csrattrs(struct hs20_osu_client *ctx, CsrAttrs *csrattrs,
			 STACK_OF(X509_EXTENSION) *exts)
{
	int i, num;

	if (!csrattrs || ! csrattrs->attrs)
		return;

#ifdef OPENSSL_IS_BORINGSSL
	num = sk_num(CHECKED_CAST(_STACK *, STACK_OF(AttrOrOID) *,
				  csrattrs->attrs));
	for (i = 0; i < num; i++) {
		AttrOrOID *ao = sk_value(
			CHECKED_CAST(_STACK *, const STACK_OF(AttrOrOID) *,
				     csrattrs->attrs), i);
		switch (ao->type) {
		case 0:
			add_csrattrs_oid(ctx, ao->d.oid, exts);
			break;
		case 1:
			add_csrattrs_attr(ctx, ao->d.attribute, exts);
			break;
		}
	}
#else /* OPENSSL_IS_BORINGSSL */
	num = SKM_sk_num(AttrOrOID, csrattrs->attrs);
	for (i = 0; i < num; i++) {
		AttrOrOID *ao = SKM_sk_value(AttrOrOID, csrattrs->attrs, i);
		switch (ao->type) {
		case 0:
			add_csrattrs_oid(ctx, ao->d.oid, exts);
			break;
		case 1:
			add_csrattrs_attr(ctx, ao->d.attribute, exts);
			break;
		}
	}
#endif /* OPENSSL_IS_BORINGSSL */
}
