Snort 2.9.2.3 pkg v. 2.5.1: minor problem

[Fesoj]

If you are using snort with

• the emergning threads rules (i.e. without downloading the Snorg.org rules)

• and have activated the sensitive data preproc

for all snort interfaces, then starting up snort will fail.

If that happens on your box, have a look at https://github.com/bsdperimeter/pfsense-packages/pull/291/files
