pNFS/flexfiles: If the layout is invalid, it must be updated before retrying
commit df3ab232e462bce20710596d697ade6b72497694 upstream.
If we see that our pNFS READ/WRITE/COMMIT operation failed, but we
also see that our layout segment is no longer valid, then we need to
get a new layout segment before retrying.
