e1000e: fix warn_on reload after phy_id error

If the driver fails to initialize the first time due to the failure in the phy_id check the kernel triggers a warn_on on the second try to load the driver because the driver did not free the msi/x resources in the first load because of the previous failure in phy_id check.

Is that all one sentence? Can I buy a comma or semi-colon, Pat? :)

More seriously, this description is not very helpful. A good description precisely outlines the _solution_ ("fix msi/x resource leak"), perhaps with a bit of concise problem description ("failure to free msi/x resources").

Your description focuses mostly on what the user/tester experiences and observes, whereas in a changeset description the most important thing to communicate is to describe the engineering change to the driver (proper release of resources).
