From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
Once the client has processed the CB_LAYOUTRECALL, but has not yet
successfully returned the layout, the server is supposed to switch to
returning NFS4ERR_RETURNCONFLICT. This patch ensures that we handle
that return value correctly.
Fixes: 183d9e7b112a ("pnfs: rework LAYOUTGET retry handling")
