drm/nouveau: Provide nouveau_bo_{pin,unpin}_locked()

Browse source

Implement pinning without locking in nouveau_bo_pin_locked(). Keep
nouveau_bo_pin() for acquiring the buffer object's reservation lock.
The new helper will be useful for implementing the GEM pin callback
with correct semantics. Same for unpin.
