igb: do not use phy ops in ethtool test cleanup for non-copper parts

Currently the igb driver is experiencing a panic due to a null function
pointer being used during the cleanup of the ethtool looback test on
fiber/serdes parts.  This patch prevents that and adds a check prior to
calling any phy function.
