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.
