Florian Westphal d3e6e285ff net: ipv4: fix rcu lockdep splat due to wrong annotation 
syzbot triggered following splat when strict netlink
validation is enabled:

net/ipv4/devinet.c:1766 suspicious rcu_dereference_check() usage!

This occurs because we hold RTNL mutex, but no rcu read lock.
The second call site holds both, so just switch to the _rtnl variant.

Reported-by: syzbot+bad6e32808a3a97b1515@syzkaller.appspotmail.com
Fixes: 2638eb8b50cf ("net: ipv4: provide __rcu annotation for ifa_list")
