[PATCH 09/10] tests/aio-multithread: Clean up global variable shadowing

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Rename the argument to avoid:

  tests/unit/test-aio-multithread.c:226:37: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
  static void test_multi_co_mutex(int threads, int seconds)
                                      ^
  tests/unit/test-aio-multithread.c:401:34: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
  static void test_multi_mutex(int threads, int seconds)
                                   ^
  tests/unit/test-aio-multithread.c:24:18: note: previous declaration is here
  static IOThread *threads[NUM_CONTEXTS];
                   ^
