  To: dev; +Cc: matan, stable

An array of the size of total operations needed for the de/compression is
reserved for ops while enqueueing, although only first burst_size entries
of the array are used.

Reduce the size of the array allocated.

Fixes: b68a82425da4 ("app/compress-perf: add performance measurement")
