livepatch: fix deferred module patching order
When applying multiple patches to a module, if the module is loaded after the patches are loaded, the patches are applied in reverse order: $ insmod patch1.ko [ 43.172992] livepatch: enabling patch 'patch1' $ insmod patch2.ko [ 46.571563] livepatch: enabling patch 'patch2' $ modprobe nfsd [ 52.888922] livepatch: applying patch 'patch2' to loading module 'nfsd' [ 52.899847] livepatch: applying patch 'patch1' to loading module 'nfsd' Fix the loading order by storing the klp_patches list in queue order.
