drm/i915/gem: Drop false !i915_vma_is_closed assertion

Browse source

Closed vma are protected by the GT wakeref held as we lookup the vma, so
we know that the vma will not be freed as we process it for the execbuf.
Instead we expect to catch the closed status of the context, and simply
allow the close-race on an individual vma to be washed away.

Longer term, the GT wakeref protection will be removed by explicit
vma.kref tracking.
