wireless-drivers fixes for 4.20 

First set of fixes for 4.20, this time we have quite a few them but
 all very small.
 
 ath9k
 
 * fix a locking regression found by a static checker
 
 wlcore
 
 * fix a crash which was a regression with wakeirq handling
 
 brcm80211
 
 * yet another fix for 160 MHz channel handling
 
 mt76
 
 * fix a longstaning build problem when CONFIG_LEDS_CLASS is disabled
 
 * don't use uninitialised mutex
 
 iwlwifi
 
 * do note that the iwlwifi merge tag (commit 4ec321c146) seems to
   contain wrong list of changes so ignore that
 
 * fix ACPI data handling, a memory leak and other smaller fixes
 
 ath10k
 
 * fix a crash during suspend which was a recent regression
