[Devel] [PATCH vz10 10/15] selftests/mqueue: fix warnings in mq_perf_tests

[Konstantin Khorenko]

  mq_perf_tests.c: In function 'perf_test_thread':
  mq_perf_tests.c:433:20: warning: variable 't' set but not used [-Wunused-but-set-variable]
    433 |         pthread_t *t;
        |                    ^
  mq_perf_tests.c: At top level:
  mq_perf_tests.c:45:14: warning: 'usage' defined but not used [-Wunused-variable]
     45 | static char *usage =
        |              ^~~~~

- Mark 'usage' with __attribute__((unused)) to fix -Wunused-variable.
- Remove unused variable 't' to fix -Wunused-but-set-variable.
