Bandwidth specification does not work with strict priority (not supported by vrouter)

Fix for qosmap not working

While refractoring vrouter-utils/ library for *nix and windows, due to
incorrect offset calculation of nlmsghdr when parsing OS specific nl
replies, qosmap was not working. Fixing the same.
