Second batch of iwlwifi patches for 4.18

Browse source 
* Some preparations for new hardware;
 * A workaround to rescan the bus for the rare situation when older
   devices become irresponsive,
 * Hardening of the firmware loading code to avoid issues with
   corrupted files;
 * A few clean-ups and bugfixes.
