[Mesa-dev] [PATCH] radv: apply xfb buffer offset at buffer binding time not later. (v2)

From: Dave Airlie <airlied at redhat.com>
In order to handle pause/resume properly, the offset should
be added to the buffer binding not to the begin/end paths.
v2: don't add offset to size
Fixes ext_transform_feedback-alignment* under zink
Fixes: b4eb029062 (radv: implement VK_EXT_transform_feedback)
