[PATCH 31/31] cfg80211: reg: improve bad regulatory warning

[Luca Coelho <luca@coelho.fi>]

From: Johannes Berg <johannes.berg@intel.com>

There's a WARN_ON here but it says nothing, and the later
dump of the regdomain aren't usually printed. As a first
step, include the regdomain code in the WARN_ON message,
just like in other similar instances.
