The ods-ksmutil key rollover command does not work correctly when rolling all keys using the --policy option

Expected behaviour:

• In 1.3.13 and 1.4.0 the command
  >ods-ksmutil key rollover --policy
  would be expected to roll all the keys on the specified policy
  Observed behaviour:
• the command appears to succeed but no keys are rolled
  Cause:
• In ksmutil.c in the cmd_rollpolicy method the variable key_type is incorrectly initialised.
  Notes:
• the command works as expected if the key type is specified. In 1.3.14 and 1.4.1 the --all flag will be explicitly required and the behaviour will be correct with that change (OPENDNSSEC-91)
