    fs/xfs: Correct NULL test
    
    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>
