NS_CLIENT_TCP_BUFFER_SIZE was 2 byte too large following the move to netmgr add associated changes to lib/ns/client.c and as a result an INSIST could be trigger if the DNS message being constructed had a checkpoint stage that fell in those two extra bytes. Adjusted NS_CLIENT_TCP_BUFFER_SIZE and cleaned up client_allocsendbuf now that the previously reserved 2 bytes are no longer used.
