Eric Dumazet 2b3ae007c6 net/packet: remove data races in fanout operations 
[ Upstream commit 94f633ea8ade8418634d152ad0931133338226f6 ]

af_packet fanout uses RCU rules to ensure f->arr elements
are not dismantled before RCU grace period.

However, it lacks rcu accessors to make sure KCSAN and other tools
wont detect data races. Stupid compilers could also play games.

Fixes: dc99f60069 ("packet: Add fanout support.")
