Jeffrey Wilcke b9359981f4 xeth: fixed nil pointer of filter retrieval
This fix addresses an issue with filters that were (possibly) not yet
added to the filter queues but were expected. I've added additional nil
checks making sure it doesn't crash and swapped the installation of the
filter around so it's installed before use.

Closes #1665
