starfire: clean up properly if firmware loading fails

netdev_open() will return without cleaning up net device or hardware state
if firmware loading fails.  This results in a BUG() on a second attempt to
bring the interface up, reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=15091>, and probably has even
worse effects if the driver is removed afterwards.

Call netdev_close() to clean up on failure.
