Local fix

• Pass key value instead of ICSF keylabel.
  

Problem summary

• An ICSF keylabel for a key stored in the CKDS was passed to
  Cipher.init(). The IBMJCECCA code was incorrectly passing this
  to a routine which only takes key values.
  

Problem conclusion

• The code is modified to check for an ICSF keylabel and pass this
  request to the correct interface.
