ext2: add warning when specifying nocheck option
The option nocheck(nocheck/check=none) is useless but considering backwards compatibility it's better to print warning for a while before completely remove from the code. This patch add proper warning message for option 'nocheck' and remove unnecessary comment/function declaration which is used for removed option 'check'.
