[PATCH 3/3] igc: Remove redundant runtime resume for ethtool ops

From: Bjorn Helgaas <bhelgaas@google.com>

8c5ad0dae93c ("igc: Add ethtool support") added ethtool_ops.begin() and
.complete(), which used pm_runtime_get_sync() to resume suspended devices
before any ethtool_ops callback and allow suspend after it completed.

Subsequently, f32a21376573 ("ethtool: runtime-resume netdev parent before
ethtool ioctl ops") added pm_runtime_get_sync() in the dev_ethtool() path,
so the device is resumed before any ethtool_ops callback even if the driver
didn't supply a .begin() callback.

Remove the .begin() and .complete() callbacks, which are now redundant
because dev_ethtool() already resumes the device.
