genl: Hold reference on correct module while netlink-dump.
netlink dump operations take module as parameter to hold reference for entire netlink dump duration. Currently it holds ref only on genl module which is not correct when we use ops registered to genl from another module. Following patch adds module pointer to genl_ops so that netlink can hold ref count on it.
