[ion] 24686: - disk.sys: Don't fail IOCTL_GET_PARTITION_INFO for Partition 0. This is perfectly valid (and needed for some code I'll add later). - IopGetDiskInformation: Treat the partition buffer as a simple PULONG array. - KeUpdateSystemTime: Fix memory addressing to silence GAS compile-time warning.
