s390/pci: reshuffle struct used to write debug data
commit 7cc8944e13c73374b6f33b39ca24c0891c87b077 upstream.
zpci_err_insn writes stale stack content to the debugfs.
Ensure that the struct in zpci_err_insn is ordered in a way that
we don't have uninitialized holes in it. In addition to that
add the packed attribute.
Fixes: 3d8258e (s390/pci: move debug messages to debugfs)
