Subject: nl80211: validate number of probe response CSA counters

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

commit ad5987b47e96a0fb6d13fea250e936aed000093c upstream.

Due to an apparent copy/paste bug, the number of counters for the
beacon configuration were checked twice, instead of checking the
number of probe response counters. Fix this to check the number of
probe response counters before parsing those.
