net: add missing data-race annotations around sk->sk_peek_off
sk_getsockopt() runs locklessly, thus we need to annotate the read
of sk->sk_peek_off.
While we are at it, add corresponding annotations to sk_set_peek_off()
and unix_set_peek_off().
Fixes: b9bb53f3836f ("sock: convert sk_peek_offset functions to WRITE_ONCE")
