ipv6: addrconf: Avoid addrconf_disable_change() using RCU read-side lock
[ Upstream commit 03e4deff4987f79c34112c5ba4eb195d4f9382b0 ]
Just like commit 4acd4945cd1e ("ipv6: addrconf: Avoid calling
netdevice notifiers with RCU read-side lock"), it is unnecessary
to make addrconf_disable_change() use RCU iteration over the
netdev list, since it already holds the RTNL lock, or we may meet
Illegal context switch in RCU read-side critical section.
