sim/netdev: eliminated RX data stream congestion in case of high TX network traffic.

Browse Source 
In case of high TX network traffic, netdriver_loop() that reads data from netdev
was invoked via up_idle() only after high TX network traffic had stopped.
That resulted in massive delay and drop of TCP ACK packets and
any other packets from netdev (tun/tap device).
