Cameron Gutman 9e347006d5 atomic: Fix infinite recursion in SDL_CompilerBarrier() fallback 
On some platforms, SDL_MemoryBarrierRelease() is defined to
SDL_CompilerBarrier(). If SDL_CompilerBarrier() is also defined to
the fallback spinlock acquire/release, then we will infinitely
recurse in SDL_UnlockSpinlock(). Avoid this by not unlocking the
temporary spinlock we create.
