4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <trond.mykleb...@hammerspace.com>
commit c1dffe0bf7f9c3d57d9f237a7cb2a81e62babd2b upstream.
If we have to retransmit a request, we should ensure that we reinitialise
the sequence results structure, since in the event of a signal
we need to treat the request as if it had not been sent.
