Currently we might arrive to bond_net_exit() with some bonds left (that were created while the module is unloading). We take care of that by destroying sysfs (the last possibility to add new bonds) and then destroying all the remaining bonds. However, we destroy the /proc/net/bonding directory before destroying those last bonds, and get a warning that we're trying to destroy a non-empty proc directory (containing /proc/net/bonding/bondX). Fix this by moving bond_destroy_proc_dir() after all the bonds are destroyed, so that we're sure that no bonds exist.
