pnfs: Fix a problem where we gratuitously start doing I/O through the MDS
If the client has to stop in pnfs_update_layout() to wait for another
layoutget to complete, it currently exits and defaults to I/O through
the MDS if the layoutget was successful.
Fixes: d03360aaf5cc ("pNFS: Ensure we return the error if someone kills...")
