Only write changed DASD attributes to rd_DASD params (#606783)
Only include option values in the rd_DASD parameter if the user has
changed the value. This should reduce the amount of data written to
zipl.conf by a reasonable amount, which should keep most use cases
from exceeding the boot parameter length limit.
