Fix emaclite in lwip202

[halferty]

This fixes an issue I encountered while running through the Digilent guide to setting up an echo server using the Arty A7 board and Vivado SDK. I made a forum post with more details here:

Hello,

In eth_link_detect function, the line

XEmacLite *xemacp = &xemacs->instance;

should be changed to

XEmacLite *xemacp = xemacs->instance;

Have a nice day
