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>
