drm/i915: add i915_address_space_fini
We already have an i915_address_space_init, so for symmetry we should
also have a _fini, plus we already open code it twice. This then also
fixes a bug where we leak the timeline for the ggtt vm.
v2: don't forget about the struct_mutex for the ggtt path.
Fixes: 80b204bce8f2 ("drm/i915: Enable multiple timelines")
