drivers: net: cpsw: fix error return code

Propagate the return value of platform_get_irq on failure.

A simplified version of the semantic match that finds the two cases where
no error code is returned at all is as follows:

// <smpl>
@@
identifier ret; expression e1,e2;
@@
(
if (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>
