nicintel_eeprom: Check UNPROG_DEVICE in 82580 shutdown

Previously shutdown function was registered conditionally for 82580,
only if the device was not UNPROG_DEVICE. This patch moves the check
for UNPROG_DEVICE into shutdown function itself, so that shutdown
function can be always registered for 82580.

This also fixes a memory leak in nicintel_ee_shutdown_82580.

No changes for i210 device init/shutdown, only for 82580.

And very importantly this unlocks API change which plans to move
register_shutdown inside register_opaque_master, similar to what's
done in CB:56103
