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;

if (...) {
