    s390/ipl: Fix incorrect initialization of len fields in nvme reipl block
    
    [ Upstream commit 9c922b73acaf39f867668d9cbe5dc69c23511f84 ]
    
    Use correct symbolic constants IPL_BP_NVME_LEN and IPL_BP0_NVME_LEN
    to initialize nvme reipl block when 'scp_data' sysfs attribute is
    being updated. This bug had not been detected before because
    the corresponding fcp and nvme symbolic constants are equal.
