fs: Replace simple_strtoul with kstrtoul in set_ihash_entries
Replace simple_strtoul() with the recommended kstrtoul() for parsing the
'ihash_entries=' boot parameter.
Check the return value of kstrtoul() and reject invalid values. This
adds error handling while preserving behavior for existing valid values,
and removes use of the deprecated simple_strtoul() helper.
