igb: Add check for invalid size to igb_get_invariants_82575()
igb: Add check for invalid size to igb_get_invariants_82575()

Recent commits have changed how EEPROM size is checked and if the size
word is misconfigured, the driver will fail to load.  This patch adds a
check for invalid size word in the EEPROM and uses default size instead
for 82576 parts.
