igb: do not allow phy sw reset code to make calls to null pointers

In the case of fiber and serdes adapters we were seeing issues with ethtool
-t causing kernel panics due to null function pointers.  To prevent this we
need to exit out of the phy reset code in the event that we do not have a
valid phy.
