[PATCH] selftests: kselftest: fix function return type

[Alakesh Haloi]

ksft_test_num function returns sum of unsigned ints and hence should
return unsigned int. This fixes the following compiler warning

In file included from sync_test.c:37:0:
../kselftest.h: In function âksft_print_cntsâ:
../kselftest.h:73:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
  if (ksft_plan != ksft_test_num())
                ^~
