[ Upstream commit 662f9a105b4322b8559d448f86110e6ec24b8738 ]
If xdr_inline_decode() fails then we end up returning ERR_PTR(0). The
caller treats NULL returns as -ENOMEM so it doesn't really hurt runtime,
but obviously we intended to set an error code here.
Fixes: d67ae825a59d ("pnfs/flexfiles: Add the FlexFile Layout Driver")
