wifi: iwlwifi: mvm: cleanup the driver state after device_powered_off

Browse Source 
If the device was powered off during suspend, we need to reload the
firmware in resume which also means that we need to reconfigure it.

It could be tempting to just set IWL_MVM_STATUS_HW_RESTART_REQUESTED
but that would leave IWL_MVM_STATUS_IN_HW_RESTART set forever since that
recovery is not managed by mac80211.

Just call iwl_mvm_restart_cleanup() from device_powered_off().
