s390/ipl: Fix incorrect initialization of nvme dump block

Initialize the correct fields of the nvme dump block.
This bug had not been detected before because first, the fcp and nvme fields
of struct ipl_parameter_block are part of the same union and, therefore,
overlap in memory and second, they are identical in structure and size.
