drivers/pnp/resource.c: Add missing pci_dev_put

Browse source 
There should be a pci_dev_put when breaking out of a loop that iterates
over calls to pci_get_device and similar functions.

This was fixed using the following semantic patch.

// <smpl>
@@
identifier d;
type T;
expression e;
iterator for_each_pci_dev;
@@

T *d;
...
for_each_pci_dev(d)
   {... when != pci_dev_put(d)
        when != e = d
(
    return d;
|
+  pci_dev_put(d);
?  return ...;
)
...}
// </smpl>
