drm/i915/perf: Invalidate OA TLB on when closing perf stream
On running several back to back perf capture sessions involving closing
and opening the perf stream, invalid OA reports are seen in the
beginning of the OA buffer in some sessions. Fix this by invalidating OA
TLB when the perf stream is closed or disabled on gen12.
