Michal Kazior f42f8eb27e ath10k: fix insufficient tracing buffer size 
Some trace messages were truncated and a kernel
splat could be seen in the log:

  WARNING: CPU: 3 PID: 0 at /devel/src/linux/drivers/net/wireless/ath/ath10k/./trace.h:114 ftrace_raw_event_ath10k_log_dbg+0x20e/0x220 [ath10k_core]()

This could be reproduced with:

  trace-cmd record -e ath10k
  ifconfig wlan0 down
  ifconfig wlan0 up

Fixes: 5c01aa3de9 ("ath10k: deduplicate wmi service ready logic")
Fixes: ca996ec566 ("ath10k: implement wmi-tlv backend")
