pNFS/flexfiles: Fix an Oopsable condition when connection to the DS fails
If the attempt to connect to a DS fails inside ff_layout_pg_init_read or
ff_layout_pg_init_write, then we currently end up clearing the layout
segment carried by the struct nfs_pageio_descriptor, causing an Oops
when we later call into ff_layout_read_pagelist/ff_layout_write_pagelist.
The fix is to ensure we return the layout and then retry.
