Matt Oliver 6be690685a ffplay: Fix realloc_texture when input texture is NULL. 
SDL_QueryTexture and SDL_DestroyTexture require that the input texture
pointer be non-null. Debug builds of SDL will correctly check for this
and break program execution. This patch fixes this by checking the
status of the texture pointer.
