igb: Fix for failure to init on some 82576 devices.
Move nvm invalid size check to before size assigned by mac_type for
82575 and later parts in get_invariants function. This fixes a problem
found on some 82576 devices where the part will not initialize because
the nvm_read function pointer ends up getting assigned to the incorrect
function.
