net: annotate sk->sk_err write from do_recvmmsg()

Browse source

[ Upstream commit e05a5f510f ]

do_recvmmsg() can write to sk->sk_err from multiple threads.

As said before, many other points reading or writing sk_err
need annotations.

Fixes: 34b88a68f2 ("net: Fix use after free in the recvmmsg exit path")
