[PATCH] make sendmsg return EDESTADDRREQ if socket is not connected and daddr was not specified

[Thomas Graf <tgraf@xxxxxxx>]

Hello

Another 1003.1 fix:

[EDESTADDRREQ]
    The socket is not connection-mode and does not have its peer
    address set, and no destination address was specified.

fixes sendmsg in ipv{4,6}/{raw,udp}
