staging: goldfish: goldfish_nand: Return correct error code

The return value of devm_kzalloc on failure of allocation of memory should
be -ENOMEM and not -1.

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

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

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

The single call site does not perform any checks on the return value, hence
no change is required at the call site.
