namespace: Replace simple_strtoul with kstrtoul to parse boot params

Browse source

Replace simple_strtoul() with the recommended kstrtoul() for parsing the
'mhash_entries=' and 'mphash_entries=' boot parameters.

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.
