Miaoqian Lin 8f92817b6f cpufreq: nforce2: fix reference count leak in nforce2 
commit 9600156bb9 upstream.

There are two reference count leaks in this driver:

1. In nforce2_fsb_read(): pci_get_subsys() increases the reference count
   of the PCI device, but pci_dev_put() is never called to release it,
   thus leaking the reference.

2. In nforce2_detect_chipset(): pci_get_subsys() gets a reference to the
   nforce2_dev which is stored in a global variable, but the reference
   is never released when the module is unloaded.

Fix both by:
- Adding pci_dev_put(nforce2_sub5) in nforce2_fsb_read() after reading
  the configuration.
- Adding pci_dev_put(nforce2_dev) in nforce2_exit() to release the
  global device reference.

Found via static analysis.
