iwlwifi: don't mess up the SCD when removing a key
When we remove a key, we put a key index which was supposed to tell the fw that we are actually removing the key. But instead the fw took that index as a valid index and messed up the SRAM of the device. This memory corruption on the device mangled the data of the SCD. The impact on the user is that SCD queue 2 got stuck after having removed keys. The message is the log that was printed is: Queue 2 stuck for 10000ms This doesn't seem to fix the higher queues that get stuck from time to time.
