Subject: cfg80211: don't WARN about two consecutive Country IE hint

commit 70dcec5a488a7b81779190ac8089475fe4b8b962 upstream.

This can happen and there is no point in added more
detection code lower in the stack. Catching these in one
single point (cfg80211) is enough. Stop WARNING about this
case.
