perf test: Reset shadow counts before loading
Otherwise load counting is an average. Without this change
duration_time in test_memory_bandwidth will alter its value if an
earlier test contains duration_time.
This patch fixes an issue that's introduced in the proposed patch:
https://lore.kernel.org/lkml/20211124015226.3317994-1-irogers@google.com/
in perf test "Parse and process metrics".
