[PATCH 0/1] MR3979: wined3d: Reference the push constant buffers.

[Stefan Dösinger]

---

I came across this in my attempts to implement nooverwrite maps based on
sysmem staging buffers when buffer storage is not available. My debug
modifications broke the fast path for update_sub_resource and the
wined3d_resource_wait() didn't do its job for the push constant buffers.
