      s390/pci: add extra padding to function measurement block
      Newer machines might use a different (larger) format for function
      measurement blocks. To ensure that we comply with the alignment
      requirement on these machines and prevent memory corruption (when
      firmware writes more data than we expect) add 16 padding bytes
      at the end of the fmb.
