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 4ec321c14693) 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
