Fixing suspend timer: where to stash io counter stats?

Already answered on IRC, but for the record: the private struct
_UDisksLinuxDriveAta in src/udiskslinuxdriveata.c seems quite
appropriate for this. In there you most probably won't even need new
internal API as all the SMART stuff shoudl be contained in that
object.

Thanks for looking into this!
