net: tcp: refresh tcp_mstamp for compressed ack in timer
For now, we refresh the tcp_mstamp for delayed acks and keepalives, but
not for the compressed ack in tcp_compressed_ack_kick().
I have not found out the effact of the tcp_mstamp when sending ack, but
we can still refresh it for the compressed ack to keep consistent.
