Subject: [PATCH] rtnetlink: wire up rtnl_net_debug_exit

From: Arnd Bergmann <arnd@...db.de>

The function is never called, but causes a build warning:

net/core/rtnl_net_debug.c:125:20: error: 'rtnl_net_debug_exit' defined but not used [-Werror=unused-function]
  125 | static void __exit rtnl_net_debug_exit(void)
      |                    ^~~~~~~~~~~~~~~~~~~
WARNING: modpost: vmlinux: section mismatch in reference: rtnl_net_debug_exit+0x1c (section: .exit.text) -> rtnl_net_debug_net_ops (section: .init.data)

Use this as the exitcall as was clearly intended and remove the __net_initdata
annotation on rtnl_net_debug_net_ops to ensure the structure remains there.

Fixes: 03fa53485659 ("rtnetlink: Add ASSERT_RTNL_NET() placeholder for netdev notifier.")
