[Mesa-dev] [PATCH] nv50, nvc0: make sure to pushbuf_refn before putting bo into pushbuf_data

[Ilia Mirkin]

Without first running the bo through pushbuf_refn, the nouveau drm
library will have uninitialized structures regarding this bo, and will
insert incorrect data.

This fixes supertuxkart 0.9 crash on start (where it ends up doing a lot
of indirect draws).
