Fixed bug 2596 - SDL_SetError fails on on NULL on systems with vsnprintf

sfalexrog

On systems with vsnprintf call SDL_SetError fails when passed a NULL as an argument. SDL's implementation checks for NULL (as seen in the commit: https://hg.libsdl.org/SDL/rev/835403a6aec8), but system implementation may crash.
