[patch 02/18] bcm43xx: Fix for oops on ampdu status

[Greg KH <greg@kroah.com>]

-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Michael Buesch <mb@bu3sch.de>

If bcm43xx were to process an afterburner (ampdu) status response, Linux would oops. The
ampdu and intermediate status bits are properly named.
