[Mesa-dev] [PATCH 2/2] loader/dri3: Don't wait for fence of old buffer when re-allocating it

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

We only need to wait for the fence before drawing to a buffer, not
before reading from it.

This might avoid hangs when re-allocating the fake front buffer, similar
to the previous change. But I haven't seen any hard evidence that this
was actually happening in practice.
