Eric Dumazet 939135ddea net: dst: annotate data-races around dst->output ...

[ Upstream commit 2dce8c52a9 ]

dst_dev_put() can overwrite dst->output while other
cpus might read this field (for instance from dst_output())

Add READ_ONCE()/WRITE_ONCE() annotations to suppress
potential issues.

We will likely need RCU protection in the future.
