BUG/MAJOR: patterns: fix double free caused by loading strings from files
A null pointer assignment was missing after a free in commit 7148ce6
(MEDIUM:
pattern: Extract the index process from the pat_parse_*() functions), causing
a double free after loading a file of string patterns.
This bug was introduced in 1.5-dev20, no backport is needed.
Thanks to Sander Klein for reporting this bug and providing the config
needed to trigger it.
