drm/i915: unload: ensure that gem is idle
When the module unloads, all users should be gone, hence all bo references
held by userspace, too. This should already result in an idle ringbuffer.
Still, be paranoid and idle gem before starting the unload dance.
Also kill the call to i915_gem_lastclose under an if (kms), it's a noop
for kms.
