Change a bounds check to handle a packet instead of letting it go.

This change reverts mod to line 1525 of GetDataHandlers.cs in
672d360e9d by Deathamx.

We couldn't think of a reason why a bounds check would ever return
false, thus not handling the packet and letting the server accept
it. Therefore, it's now true.

In the future, we need to document handling better.
