3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Yan, Zheng" <zheng.z.yan@xxxxxxxxx>
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.
