[PATCH] cfg80211: fix station info handling bugs

[Johannes Berg]

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

Fix two places where the structure isn't initialized to zero,
and thus can't be filled properly by the driver.

Fixes: 4a4b8169501b ("cfg80211: Accept multiple RSSI thresholds for CQM")
Fixes: 9930380f0bd8 ("cfg80211: implement IWRATE")
Signed-off-by: Johannes Berg <johannes.b...@intel.com>

Dave, can you apply this as an exception? I'm not really expecting
any other patches to show up now, and seems easier to have a single
patch than a whole pull request (especially now that patchwork seems
to be swallowing mine ...)
