r8169: fix suspend/resume for down interface

Browse Source 
The PM hooks are no-op if the r8169 interface is down (i.e. !IFF_UP).
However, as the chipset is enabled, the device will not work after a
suspend/resume cycle. The patch always issue the required PCI suspend
sequence and removes the module unload/reload workaround.
