Correct eeprom restore issues.

[vthoang]

Option --restore fails different detection. "new" is overwritten by ee_encode (old's values) right after loading from file. Moved ee_encode into else scope.

Factory configuration location 0x80 thru 0x9f of eeprom does not change on write. This causes an invalid crc value when loading eeprom from a different device. Account for difference and recompute crc.
