3.13.11-ckt15 -stable review patch.  If anyone has any objections, please let 
me know.

------------------

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

commit 28a9bc68124c319b2b3dc861e80828a8865fd1ba upstream.

When writing the code to allow per-station GTKs, I neglected to
take into account the management frame keys (index 4 and 5) when
freeing the station and only added code to free the first four
data frame keys.

Fix this by iterating the array of keys over the right length.
