Leo Yan April 3, 2021, 7:23 a.m. UTC 
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.
