Subject: [PATCH] r8169: Enable suspend when device is idle from boot.

The r8169 driver supports power management and correctly transitions
from active to suspend when link transitions from connected to
disconnected.  However, if link is not connected at boot the device
remains active after the initial probe.

This change adds a check of the link status to the idle pm_op that
will schedule a suspend if inactive.
