ikev1: Fix prefix length of vendor ID MS NT5 ISAKMPOAKLEY

Before commit 6c49ddfbca ("ike: Add additional Vendor IDs for
third-party implementations") the prefix length of vendor ID
MS NT5 ISAKMPOAKLEY was hardcoded to 16. Change the prefix length
accordingly.

Fixes: 6c49ddfbca72 ("ike: Add additional Vendor IDs for third-party implementations")
