[PATCH 10/10] mac80211: further improve "no supported rates" warning

From: Johannes Berg <redacted>

Allow distinguishing the non-station case from the case of a
station without rates, by using -1 for the non-station case.
This value cannot be reached with a station since that many
legacy rates don't exist.
