pNFS: Always set NFS_LAYOUT_RETURN_REQUESTED with lo->plh_return_iomode
When setting the layout return mode, we must always also set the NFS_LAYOUT_RETURN_REQUESTED flag to ensure that we send a layoutreturn. Otherwise pnfs_error_mark_layout_for_return() could set the mode, but fail to send the layoutreturn because another is already in flight.
