[PATCH 4.2.y-ckt 187/211] sctp: also copy sk_tsflags when copying the socket

[Kamal Mostafa]

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marcelo Ricardo Leitner <marcelo.leitner@xxxxxxxxx>

[ Upstream commit 50a5ffb1ef535e3c6989711c51b5d61b543a3b45 ]

As we are keeping timestamps on when copying the socket, we also have to
copy sk_tsflags.

This is needed since b9f40e21ef42 ("net-timestamp: move timestamp flags
out of sk_flags").
