fib_nh_common_init() before alloc_percpu_gfp() within fib6_nh_init()\nbut forgot to add cleanup for fib6_nh->nh_common.nhc_pcpu_rth_output in\ncase it fails to allocate fib6_nh->rt6i_pcpu, resulting in memleak.\n\nLet's call fib_nh_common_release() and clear nhc_pcpu_rth_output in the\nerror path.\n\nNote that we can remove the fib6_nh_release() call in nh_create_ipv6()\nlater in
