drm/ttm: fix locking in vmap/vunmap TTM GEM helpers
I've stumbled over this while reviewing patches for DMA-buf and it looks
like we completely messed the locking up here.
In general most TTM function should only be called while holding the
appropriate BO resv lock. Without this we could break the internal
buffer object state here.
Only compile tested!
