Trond Myklebust dcc00106c3 NFSv4/pNFS: Do not fail I/O when we fail to allocate the pNFS layout 
[ Upstream commit 3764a17e31 ]

Commit 587f03deb6 caused pnfs_update_layout() to stop returning ENOMEM
when the memory allocation fails, and hence causes it to fall back to
trying to do I/O through the MDS. There is no guarantee that this will
fare any better. If we're failing the pNFS layout allocation, then we
should just redirty the page and retry later.
