fsl: update CRC after setting EEPROM identifier

The "mac id" command is used to initialize the EEPROM data to a specific
format, but it was not updating the CRC.  This didn't cause any real
problems, because writing the data to the EEPROM will always update the
CRC anyway, but it did result in a bogus CRC warning.
