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

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

From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

commit 0297ea17bf7879fb5846fafd1be4c0471e72848d upstream.

When the driver cannot start the AP or when the assignement
of the beacon goes wrong, we need to unassign the vif.
