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

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

From: "Yan, Zheng" <zheng.z.yan@intel.com>

commit eb1b8af33c2e42a9a57fc0a7588f4a7b255d2e79 upstream.

Aborted requests usually get cleared when the reply is received.
If MDS crashes, no reply will be received. So we need to cleanup
aborted requests when re-sending requests.
