The log below seems strange. Actually we have a patch to fix this issue
https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/drivers/net/wireless/ath/ath12k?id=a49732b1f1f8128608b1192c562880dd29037c06. 
So the question is are you still seeing this log with latest Kalle's 
ath.git?

[ 1132.255250] ath12k_pci 0000:01:00.0: Unknown htt tx status 8

Current logs don't provide enough info.  Could you reproduce it with 
full ath12k log and IWD log enabled and share them to us?
For ath12k, first unload module and then reload.
	modprobe -r ath12k
	modprobe ath12k dyndbg=+pflmt debug_mask=0xffffffff
For IWD, simply add '-d' option when starting it. You may directly add 
it to the systemd service entry if you like. See 
https://iwd.wiki.kernel.org/debugging

Better if you could also capture air sniffer as well.
