Commit dc09766c755c {"wifi: wireless: warn on most wireless extension
usage") introduces a warning when wireless extensions are used with
cfg80211 drivers. Although such a warning is desirable, the current
implementation overflows the dmesg buffer with thousands of warnings,
all of which are the same. A WARN_ONCE() call is sufficient.
