ipv6: make sure to initialize sockc.tsflags before first use
[ Upstream commit d515684d78148884d5fc425ba904c50f03844020 ]
In the case udp_sk(sk)->pending is AF_INET6, udpv6_sendmsg() would
jump to do_append_data, skipping the initialization of sockc.tsflags.
Fix the problem by moving sockc.tsflags initialization earlier.
The bug was detected with KMSAN.
Fixes: c14ac9451c34 ("sock: enable timestamping using control messages")
