Eric Dumazet f49ce3b36f tcp_metrics: add missing barriers on delete
[ Upstream commit cbc3a153222805d65f821e10f4f78b6afce06f86 ]

When removing an item from RCU protected list, we must prevent
store-tearing, using rcu_assign_pointer() or WRITE_ONCE().

Fixes: 04f721c671656 ("tcp_metrics: Rewrite tcp_metrics_flush_all")
