mtd: mtdsuper: replace simple_strtoul with kstrtouint

Modernize string-to-number conversion in mtdsuper.c by replacing
simple_strtoul with kstrtouint. This change provides proper type safety
for MTD device numbers which are non-negative integers.

Using kstrtouint avoids unsigned long to int conversion and is more
appropriate for device indices. The debug output format specifier is
updated to %u for unsigned int.
