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.

Fixes: f6a1491403 ("kcsan: Switch to KUNIT_CASE_PARAM for parameterized tests")
