It's needed by some drivers, e.g. mt7925, see:

+Subject: [PATCH] wifi: mac80211: warn only once on AP probe
+
+We should perhaps support this API for MLO, but it's not
+clear that it makes sense, in any case then we'd have to
+update it to probe the correct BSS.
+
+For now, if it happens, warn only once so that we don't
+get flooded with messages if the driver misbehaves and
+calls this.
