Pass a struct devdesc to the format commands. Use proper type rather
than doing weird type-punning that happened to work because the size
was right. We copied a zfs devdesc into a disk_devdesc and then after
passing through a NULL pointer reinterpreted it as a
zfs_devdesc. Instead, pass the base devdesc around and 'upcase' when
we know the types are right.
This has the happy side effect of fixing a gcc warning about bad
type punning.
