Some fixes in iwlwifi for 4.13

Browse Source 
* Some simple PCI HW ID fix-ups and additions for family 9000;
 * A couple of bugzilla fixes:
   - Remove a bogus warning message with new FWs (196915)
   - Don't allow illegal channel options to be used (195299)
 * A fix for checksum offload in family 9000;
 * A fix serious throughput degradation in 11ac with multiple streams;
 * An old bug in SMPS where the firmware was not aware of SMPS changes;
