init: Replace simple_strtoul() with kstrtouint() in root_delay_setup() 

Replace deprecated simple_strtoul() with kstrtouint() for better error
handling and input validation. Return 0 on parsing failure to indicate
invalid parameter, maintaining existing behavior for valid inputs.

The simple_strtoul() function is deprecated in favor of kstrtoint()
family functions which provide better error handling and are recommended
for new code and replacements.
