Fix failure during enable/disable of features
vnet_feature_enable_disable_with_index() checks the return status of vnet_config_{add,del}_feature(). If the config string heap index returned is the same index that was in use prior to the add/delete, it is concluded that a failure occurred and processing of the feature stops. Sometimes the config index that is returned can legitimately be the same index that was in used before the add/delete. The old list of features can have its heap entry deallocated before a new entry for the new list is allocated. The heap entry for the new list can be the entry that was deallocated while deleting the old one. Make vnet_config_{add,del}_feature() return ~0 on failure. Look for that return value as an indication that an error occurred in vnet_enable_disable_feature_by_index().
