blkiomon: fix unaligned accesses on ia64

commit 7aa3ebcec011bfe9cc60d6476252c03376a37551 packed
the blkiomon_stat structure so that traces from one
arch could be analyzed on another (in truth only x86
is different, at least from x86_64/ia64/ppc/ppc64/s390/s390x)

Moving the __u32 device member instead of a new padding field should be
fine.
