extmod/network_wiznet5k: Properly enable socket buffers for W5100(S).

Browse Source 
The W5100 and W5100S only have 4 available sockets and 16kB of socket
buffer.  Allocating 16kB to either the receive or transmit buffer of a
single socket is not allowed, so the current setup does not change the
allocation for socket 0 from the reset default.  ctlwizchip is returning -1
to indicate the error, but the response isn't being inspected and probably
doesn't need to be.
