dcache: Replace simple_strtoul with kstrtoul in set_dhash_entries 



Replace simple_strtoul() with the recommended kstrtoul() for parsing the
'dhash_entries=' boot parameter.

Check the return value of kstrtoul() and reject invalid values. This
adds error handling while preserving behavior for existing values, and
removes use of the deprecated simple_strtoul() helper.
