pNFS/filelayout: fix cheking if a layout is striped
A layout can still be striped with num_fh = 1 as it is perfectly possible
that both MDS and DSs can handle the same filehandle. Hence check according
to stripe_count > 1, which is the correct check to begin with.
We should not be called with flseg->dsaddr = NULL, but if for some reason
we do, return our best guess with is flseg->num_fh > 1.
