Fixed bug 2657 - Memory leak in GL_CreateTexture function

Nitz

In GL_CreateTexture function:

if (GL_CheckError("glGenTexures()", renderer) < 0) {
        SDL_free(data);
        return -1;
    }

Here only data is getting free but data->pixels getting leak.
So have to free data->pixels before free data.
