caif: Fix for a race in socket transmit with flow control.
Kill faulty checks on flow-off leading to connection drop at race conditions. caif_socket checks for flow-on before transmitting and goes to sleep or return -EAGAIN upon flow stop. Remove faulty subsequent checks on flow-off leading to connection drop. Also fix memory leaks on some of the errors paths.
