FROMLIST: wifi: ath10k: filter non-UTF testmode events

[linghuiwu-star]

When UTF monitor is enabled, ath10k forwards WMI events to nl80211 testmode. Non-UTF events can therefore be delivered to userspace and confuse FTM tools which expect only UTF responses.

Only forward known UTF event IDs from WMI event namespaces that route events through ath10k_tm_event_wmi(), and drop other WMI events while UTF monitor is active. READY events are still handled by the normal WMI receive path.

#	Error	File:Line	PR-introduced?	Root Cause
1	'WMI_TLV_PDEV_UTF_EVENTID' undeclared	drivers/net/wireless/ath/ath10k/testmode.c:33	Yes	PR adds new function ath10k_tm_is_utf_event() that references undefined constant WMI_TLV_PDEV_UTF_EVENTID
2	control reaches end of non-void function [-Werror=return-type]	drivers/net/wireless/ath/ath10k/testmode.c:34	Yes	Cascading error from Error #1 — incomplete return statement due to undeclared identifier

Verdict

Both errors are introduced by this PR. The patch references a WMI event ID constant that does not exist in the kernel headers.
