Revert "nl80211: fixes for event reordering." 



This reverts commit 826d3568.

Key management offload (LFR3) cannot be dependent on kernel changes
that have not yet been up-streamed.  Therefore, all kernel support
for key management offload needs to be reverted until the open source
version of kernel support for key management offload is available.
