lwip: Fix bug: Clear MSG_NOSIGNAL flag when calling send().
Lwip 2.1.2 added a new assertion to ensure that no unsupported flags
are being sent to lwip_sendmsg(). MSG_NOSIGNAL is one of these flags
and name resolving stopped working.
* lwip/socket-ops.c: lwip_S_socket_send():
Clear MSG_NOSIGNAL to ensure is not sent to lwip_sendmsg().
