[Devel] [PATCH vz10 13/15] selftests/prctl: remove unused variable 'j' in set-process-name

[Konstantin Khorenko]

  set-process-name.c: In function 'check_name':
  set-process-name.c:61:13: warning: variable 'j' set but not used [-Wunused-but-set-variable]
     61 |         int j;
        |             ^

Remove unused 'j' to fix -Wunused-but-set-variable warning.
The snprintf() return value is not needed here.
