The divide by zero bug you fixed was caused by ERF reporting a ticks per second
value greater than 1.000.000.000 in its interface info structure.

Since when reading ERF into Wireshark we convert down to nanosecond resolution
there is no point reporting a higher resolution than this.

The patch just changes the reported resolution to nanoseconds. This is just in
case, not currently causing an exception.
