Lidong Chen 8e6e87e792 kern/partition: Add sanity check after grub_strtoul() call
The current code incorrectly assumes that both the input and the values
returned by grub_strtoul() are always valid which can lead to potential
errors. This fix ensures proper validation to prevent any unintended issues.

Fixes: CID 473843
