netfilter: ctnetlink: helper modules load-on-demand support
This patch adds module loading for helpers via ctnetlink. * Creation path: We support explicit and implicit helper assignation. For the explicit case, we try to load the module. If the module is correctly loaded and the helper is present, we return EAGAIN to re-start the creation. Otherwise, we return EOPNOTSUPP. * Update path: release the spin lock, load the module and check. If it is present, then return EAGAIN to re-start the update. This patch provides a refactorized function to lookup-and-set the connection tracking helper. The function removes the exported symbol __nf_ct_helper_find as it has not clients anymore.
