See detailed explanation of why this is needed in commit eb60a89bc3a.
This spot was missed/overlooked. Basically as a result of the fact
that BEGIN_* ends up calling PUSH_SPACE, which in turn adds an extra 8
to the requested amount, we have to be mindful of that when doing bare
nouveau_pushbuf_space calls.
Reportedly this fixes some crashes when replaying a hitman trace taken
on radeonsi.
Fixes: eb60a89bc3a ("nouveau: take extra push space into account for
pushbuf_space calls")
