3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit 586e01ededf9b713a1512dd658806791a7ca1a50 upstream.
Even when connecting to an AP that doesn't support VHT,
and even when the local device doesn't support it either,
the downgrade message gets printed. Suppress the message
if HT and/or VHT is disabled.
