Ticket 48398 - Coverity defect 13352 - Resource leak in auditlog.c
Bug Description: config_get_auditfaillog allocates a char* ptr and returns it.
This if statement doesn't free that.
Fix Description: Create a new char* variable to allocate the result of
config_get_auditfaillog into, and then ensure we free it after we are done.
