arch/cris: add a missing iounmap

An extra error handling label is needed for the case where the ioremap has
succeeded.

The problem was detected using the following semantic match
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
type T,T1,T2;
identifier E;
statement S;
expression x1,x2;
constant C;
int ret;
@@

  T E;
  ...
* E = ioremap(...);
  if (E == NULL) S
  ... when != iounmap(E)
      when != if (E != NULL) { ... iounmap(E); ...}
      when != x1 = (T1)E
  if (...) {
    ... when != iounmap(E)
        when != if (E != NULL) { ... iounmap(E); ...}
        when != x2 = (T2)E
(
*   return;
|
*   return C;
|
*   return ret;
)
  }
