  Fixed compiler warning
  
  ```
   ./src/thread/pthread/SDL_syssem.c:140:12: warning: variable 'retval' is used uninitialized whenever 'while' loop exits because its condition is false [-Wsometimes-uninitialized]
      while (sem_trywait(&sem->sem) != 0) {
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~
  ./src/thread/pthread/SDL_syssem.c:149:12: note: uninitialized use occurs here
      return retval;
             ^~~~~~
  ./src/thread/pthread/SDL_syssem.c:140:12: note: remove the condition if it is always true
      while (sem_trywait(&sem->sem) != 0) {
  ```
  
  This was a legitimate bug, thank you clang!
