drm/xe: Call invalidation_fence_fini for PT inval fences in error state
Invalidation_fence_init takes a PM reference, which is released in its
_fini counterpart, so we need to make sure that the latter is called,
even if the fence is in an error state.
Since we already have a function that calls _fini() and signals the
fence in the tlb inval code, we can expose that and call it from the PT
code.
Fixes: f002702290fc ("drm/xe: Hold a PM ref when GT TLB invalidations are inflight")
