i965: Don't enable reset notification support on Gen4-5.
arekm reported that using Chrome with GPU acceleration enabled on GM45 triggered the hw_ctx != NULL assertion in brw_get_graphics_reset_status. We definitely do not want to advertise reset notification support on Gen4-5 systems, since it needs hardware contexts, and we never even request a hardware context on those systems.
