From e2a696a4cd93c2dbe445243de48ed478fbdb8009 Mon Sep 17 00:00:00 2001

Subject: i965: Remove early release of DRI2 miptree
References: bfo#86281 bko#349519
intel_update_winsys_renderbuffer_miptree() will release the existing
miptree when wrapping a new DRI2 buffer, so we can remove the early
release and so prevent a NULL mt dereference should importing the new
DRI2 name fail for any reason. (Reusing the old DRI2 name will result
in the rendering going astray, to a stale buffer, and not shown on the
screen, but it allows us to issue a warning and not crash much later in
innocent code.)
