The {7, {1300, 2700, 1444, 3000} } is a correct value.
The 1440 is report from firmware, its a wrong value, it has fixed in
firmware.
If change it to dev_warn_once, then it will have no chance to find the
other wrong values which report by firmware, and it indicate
a wrong value to mac80211/cfg80211 and lead "iw wlan0 station dump" get
a wrong bitrate.
