iwlwifi: update gen3 interrupts - sw error and image response
In 22560 devices the ROM sendis an interrupt to the host
once the IML reading is done.
Handle this interrupt, and indicate sw error in case the
value is fail.
Additionally, the cause for sw error in 22560 devices
have been changed, so update the cause list.
