ZFS fails with error 6 on upgrade to 11.1

[Goran Tepšić]

Couple of days ago I had issue with upgrading to 11.1 where I tried a bit
exotic way of upgrading by creating boot environment, mounting it and
running freebsd-update to send files to that boot environment's directory.
After I tried to boot, ZFS complained.

I tried couple of things to recover but I think 'zfs set cachefile
/boot/zfs/zpool.cachefile' actually saved my 🥓. Not entirely positive but
worth trying.

Sure:

That bootfs is my currently working dataset.  I selected the
dataset with 11.1 using the boot loader's menu.

I tried setting bootfs to `ssd/ROOT/freebsd11.1.0` to see if
that would make a difference, but it didn't.
