As flower rules are added, they are given a stats ID based on the number of rules that can be supported in firmware. Only after the initial allocation of all available IDs does the driver begin to reuse those that have been released. The initial allocation of IDs was modified to account for multiple memory units on the offloaded device. However, this introduced a bug whereby the counter that controls the IDs could be decremented before the ID was assigned (where it is further decremented). This means that the stats ID could be assigned as -1/0xfffffff which is out of range. Fix this by only decrementing the main counter after the current ID has been assigned.
