Hi all,

based on my current theory on how a deadlock could happen in the
buffer allocation code, these two patches should fix the deadlock
without having a use-after-free.

I'm still working on a way to clean up the ttm_bo_init sequence
overall, but I'm separating these two out for a hopefully quick fix,
since in my book use-after-frees are worse than deadlocks.

Samuel, I'd very much appreciate if you could check that the
deadlocks in Hitman remain fixed with these two patches.
