mm: debug_page_alloc: fix type mismatch for debug_guardpage_minorder
The debug_guardpage_minorder local variable is declared as unsigned int,
but debug_guardpage_minorder_setup() uses unsigned long and kstrtoul() to
parse the value.
Use kstrtouint() with unsigned int local variable to match the actual type
of _debug_guardpage_minorder. Also fix the format specifier from %lu to
%u accordingly.
