Yick Xie 06fdb177a0 udp: preserve the connected status if only UDP cmsg 
commit 680d11f6e5 upstream.

If "udp_cmsg_send()" returned 0 (i.e. only UDP cmsg),
"connected" should not be set to 0. Otherwise it stops
the connected socket from using the cached route.

Fixes: 2e8de85763 ("udp: add gso segment cmsg")
