anv: fix xfb usage with rasterizer discard

Browse Source 
in the initial implementation, a stream like:

* CmdBeginTransformFeedbackEXT
* CmdSetRasterizerDiscardEnableEXT
* CmdDraw
* CmdEndTransformFeedbackEXT
* CmdBeginTransformFeedbackEXT
* CmdDraw
* CmdEndTransformFeedbackEXT

would never enable transform feedback, as it only checked for the change
in rasterizer_discard state

Fixes: 4d531c67df ("anv: support rasterizer discard dynamic state")
