tcp: annotate data races in __tcp_oow_rate_limited()

Browse source

[ Upstream commit 998127cdb4 ]

request sockets are lockless, __tcp_oow_rate_limited() could be called
on the same object from different cpus. This is harmless.

Add READ_ONCE()/WRITE_ONCE() annotations to avoid a KCSAN report.

Fixes: 4ce7e93cb3 ("tcp: rate limit ACK sent by SYN_RECV request sockets")
