Julia Lawall 3ee7451a02 mtd: ts5500_flash: avoid calling map_destroy on NULL
map_destroy dereferences its argument.  The call is furthermore only
reachable when this argument is NULL.  Thus the call is dropped.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression *x;
@@

*if (x == NULL)
{ ...
* map_destroy(x);
  ...
  return ...;
}
// </smpl>
