svga: Check rasterization state object before checking poly_stipple_enable
Sometimes rasterization state object could be empty. This is causing
segfault on hw8,9,10 for some traces.
This patch fixes enemy_territory_quake_wars_high,
enemy_territory_quake_wars_low, etqw-demo, lightsmark2008, quake1
glretrace crashes on hw 8,9,10.
Tested with mtt-glretrace and mtt-piglit.
