Eric Dumazet 99ea48af7b net: prevent load/store tearing on sk->sk_stamp
[ Upstream commit f75359f3ac ]

Add a couple of READ_ONCE() and WRITE_ONCE() to prevent
load-tearing and store-tearing in sock_read_timestamp()
and sock_write_timestamp()

This might prevent another KCSAN report.

Fixes: 3a0ed3e961 ("sock: Make sock->sk_stamp thread-safe")
