Summary
net: fix possible store tearing in neigh_periodic_work()
Details

In the Linux kernel, the following vulnerability has been resolved:

net: fix possible store tearing in neighperiodicwork()

While looking at a related syzbot report involving neighperiodicwork(), I found that I forgot to add an annotation when deleting an RCU protected item from a list.

Readers use rcudeference(*np), we need to use either rcuassignpointer() or WRITEONCE() on writer side to prevent store tearing.

I use rcuassignpointer() to have lockdep support, this was the choice made in neighflushdev().
