[ Upstream commit 93b7f7ad ] Currently, when IO to DS fails, client returns the layout and retries against the MDS. However, then on umounting (inode eviction) it returns the layout again. This is because pnfs_return_layout() was changed in commit d78471d3 ("pnfs/blocklayout: set PNFS_LAYOUTRETURN_ON_ERROR") to always set NFS_LAYOUT_RETURN_REQUESTED so even if we returned the layout, it will be returned again. Instead, let's also check if we have already marked the layout invalid.
