qlogicpti: Return correct error code

The return value of of_ioremap on failure should be -ENODEV and not
-1.

Found using Coccinelle. A simplified version of the semantic patch
used is:

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

e = of_ioremap(...);
if (e == NULL) {
...
return
- -1
+ -ENODEV
;
}
//</smpl>

The single call site only checks that the return value is less than 0,
hence no change is required at the call site.
