perf arm-spe: Don't wait for PERF_RECORD_EXIT event
When decode Arm SPE trace, it waits for PERF_RECORD_EXIT event (the last perf event) for processing trace data, which is needless and even might cause logic error, e.g. it might fail to correlate perf events with Arm SPE events correctly. So this patch removes the condition checking for PERF_RECORD_EXIT event.
