iwlwifi: mvm: fix an out-of-bound access


commit ba3224db upstream.

The index for the elements of the ACPI object we dereference
was static. This means that if we called the function twice
we wouldn't start from 3 again, but rather from the latest
index we reached in the previous call.
This was dutifully reported by KASAN.

Fix this.
