Description of changes

According to a ZFS issue about hibernation causing data corruption:

The way this happens is if the system force imports a pool that was suspended during hibernation. I've had this happen twice on NixOS and I'd like to avoid having this happen again, to me or others.

To do this I've added an assertion that makes sure you can't have forceImportRoot or forceImportAll enabled with allowHibernation.

Will try to review it soon, but @infinisil input at #171680 (comment) (sorry for not responding, busy with RL) maybe beter than mine here, he even suggest an approach that may prevent this type of thing happening.

According to a ZFS issue about hibernation causing data corruption:
openzfs/zfs#12842

The way this happens is if the system force imports a pool that was
suspended during hibernation. I've had this happen twice on NixOS and
I'd like to avoid having this happen again, to me or others.

To do this I've added an assertion that makes sure you can't have
`forceImportRoot` or `forceImportAll` enabled with `allowHibernation`.
