Subject: t/io_uring: check for valid clock_index and finish state for stats
X-Git-Tag: fio-3.29~76

t/io_uring: check for valid clock_index and finish state for stats

If the clock_index isn't non-zero, it's not valid and we should disregard
the sample. Ditto if an exit signal has been sent, we're done at that
point and aren't interested in the last samples.
