processppp: fix IP log when tunnel IP source change

Browse source 
fmtaddr formats the string to a static buffer that must be selected
manually, but this log message was re-using the same buffer.

Use another index for 2nd IP so we get to know which is what.

Fixes: 2429969bd04d ("Add L2TP offloading support")
