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

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

From: Alexander Usyskin <alexander.usyskin@intel.com>

commit 22b987a325701223f9a37db700c6eb20b9924c6f upstream.

Link must be reset in case the fw doesn't
respond to client disconnect request.
We did charge the timer only in irq path
from mei_cl_irq_close and not in mei_cl_disconnect
