loader: zfs reader vdev_probe should check for minimum device size
The smallest device in the pool we can have is 64MB, since we are trying to walk all four labels to find the most up to date uberblock, this limit will also give us good method to check if we even should attempt to probe.
Enforcing the check also will make sure we are not getting wrapped while calculating the label offset.
Also, after label check, we should verify if we actually got any UB or not.
