drm/i915: Remove wrong warning from i915_gem_context_clean

commit e9f24d5fb7cf3628b195b18ff3ac4e37937ceeae

    drm/i915: Clean up associated VMAs on context destruction

Introduced a wrong assumption that all contexts have a ppgtt
instance. This is not true when full PPGTT is not active so
remove the WARN_ON_ONCE from the context cleanup code.
