drm/i915: Add object locking to i915_gem_evict_for_node and i915_gem_evict_something, v2.

Browse source

Because we will start to require the obj->resv lock for unbinding,
ensure these vma eviction utility functions also take the lock.

This requires some function signature changes, to ensure that the
ww context is passed around, but is mostly straightforward.

Previously this was split up into several patches, but reworking
should allow for easier bisection.

Changes since v1:
- Handle evicting dead objects better.
