e1000e: power off PHY after reset when interface is down

Some Phys supported by the driver do not remain powered off across a reset
of the device when the interface is down, e.g. on 82571, but not on 82574.
This patch powers down (only when WoL is disabled) the PHY after a reset if
the interface is down and the ethtool diagnostics are not currently running.

The ethtool diagnostic function required a minor re-factor as a result, and
the e1000_[get|put]_hw_control() functions are renamed since they are no
longer static to netdev.c as they are needed by the ethtool diagnostics.
A couple minor whitespace issues were cleaned up, too.
