kcsan: Fix printk format string
Printing a 'long' variable using the '%d' format string is wrong and causes a warning from gcc: kernel/kcsan/kcsan_test.c: In function 'nthreads_gen_params': include/linux/kern_levels.h:5:25: error: format '%d' expects argument of type 'int', but argument 3 has type 'long int' [-Werror=format=] Use the appropriate format modifier.
