====================
r8169: mark device as detached in PCI D3 and improve locking

Mark the netdevice as detached whenever parent is in PCI D3hot and not
accessible. This mainly applies to runtime-suspend state.
In addition take RTNL lock in suspend calls, this allows to remove
the driver-specific mutex and improve PM callbacks in general.
