[PATCH 4.11 190/197] pNFS/flexfiles: Check the result of nfs4_pnfs_ds_connect

[Greg Kroah-Hartman]

4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

commit 260f32adb88dadfaac29f47f761a088238ca164c upstream.

The check in nfs4_ff_layout_prepare_ds() seems to be missing.
