kselftest: ksft_test_num return type should be unsigned

bonzini · shuahkh · commit 3c01655ac82e · 2020-07-06T15:07:47.000-06:00
Fixes a compiler warning:

In file included from sync_test.c:37:
../kselftest.h: In function ‘ksft_print_cnts’:
../kselftest.h:78:16: warning: comparison of integer expressions of different signedness: ‘unsigned int’ and ‘int’ [-Wsign-compare]
  if (ksft_plan != ksft_test_num())
                ^~
