s390/pci: Adjust alignment in insn trace

Currently we have 64bit wide fields start at odd byte-offsets in the
insn traces for pci_error in the s390dbf debug area, which are hard to
decode in hex dumps. At the same time, trace entries are padded at the
end.

Drop the packed attribute on the struct definition to exploit the
compiler's natural alignment, introduce explicit padding before and
after the 64bit fields for humans, and add a static assertion to avoid
accidental overruns of 2 lines in the s390dbf trace.
