NFSv4.1/pnfs: Ensure we handle the error NFS4ERR_RETURNCONFLICT
[ Upstream commit 037e56a22ff37f9a9c2330b66cff55d3d1ff9b90 ]
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")
