[PATCH 11/11] fs/xfs: Correct NULL test

[Julia Lawall <julia@xxxxxxx>]

From: Julia Lawall <julia@xxxxxxx>

Test the value that was just allocated rather than the previously tested one.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r@
expression *x;
expression e;
identifier l;
@@

if (x == NULL || ...) {
    ... when forall
    return ...; }
... when != goto l;
    when != x = e
    when != &x
*x == NULL
// </smpl>
